b87df9043c configure, meson: move membarrier test to meson
The test is a bit different from the others, in that it does not run
if $membarrier is empty.  For meson, the default can simply be disabled;
if one day we will toggle the default, no change is needed in meson.build.

bb7cb3ad29 configure: do not create roms/seabios/config.mak if SeaBIOS not present
If roms/seabios/Makefile is not present, the configure script
is not creating the roms/seabios directory anymore (commit
5dce7b8d8c, "configure: remove DIRS", 2021-12-18); thus, creating
roms/seabios/config.mak fails.

The easiest thing to do is to not create the file, since it will not

by the s390-ccw firmware build, and it adds a default if configure
omitted it), and use meson-buildoptions.sh to turn

b915a2f15c configure: do not set bsd_user/linux_user early
Similar to other optional features, leave the variables empty and compute
the actual value later.  Use the existence of include or source directories
to detect whether an OS or CPU supports respectively bsd-user and linux-user.

For now, BSD user-mode emulation is buildable even on TCI-only
architectures.  This probably will change once safe signals are
brought over from linux-user.

3765068947 configure: simplify creation of plugin symbol list
--dynamic-list is present on all supported ELF (not Windows or Darwin)
platforms, since it dates back to 2006; -exported_symbols_list is
likewise present on all supported versions of macOS.  Do not bother

Remove the file creation from configure as well: for Darwin, move the
the creation of the Darwin-formatted symbols to meson; for ELF, use the
file in the source path directly and switch from -Wl, to -Xlinker to
not break weird paths that include a comma.

a5730b8bd3 block/file-posix: Simplify the XFS_IOC_DIOINFO handling
The handling for the XFS_IOC_DIOINFO ioctl is currently quite excessive:
This is not a "real" feature like the other features that we provide with
the "--enable-xxx" and "--disable-xxx" switches for the configure script,
since this does not influence lots of code (it's only about one call to
xfsctl() in file-posix.c), so people don't gain much with the ability to
disable this with "--disable-xfsctl".
It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition
on our own, so we can completely get rid of the header dependency and
thus the related code in the configure script.

dfcf900ba6 configure, meson.build: Mark support for loongarch64 hosts
Example output of `uname -a` on an initial Gentoo LA64 port, running
the upstream submission version of Linux (with some very minor patches
not influencing output here):

> Linux <hostname> 5.14.0-10342-g37a00851b145 #5 SMP PREEMPT Tue Aug 10 12:56:24 PM CST 2021 loongarch64 GNU/Linux

And the same on the vendor-supplied Loongnix 20 system, with an early
in-house port of Linux, and using the old-world ABI:

> Linux <hostname> 4.19.167-rc5.lnd.1-loongson-3 #1 SMP Sat Apr 17 07:32:32 UTC 2021 loongarch64 loongarch64 loongarch64 GNU/Linux

So a name of "loongarch64" matches both, fortunately.

4da270be1c configure: unify x86_64 and x32
The only difference between the two, as far as either configure or
Meson are concerned, is in the multilib flags passed to the compiler.

For QEMU, this fixes the handling of TYPE_OLDDEVT in
include/exec/user/thunk.h and enables testing of dirty ring buffer,
because both are using HOST_X86_64.

For tests/tcg, this means that on a hypothetical x32 host the
cross compiler will not be used to build the tests.

For tests/tcg, specify the endianness explicitly on the command line;
for configure, do the same so that it is possible to have --cpu=ppc64le
on a bigendian system or vice versa.  Apart from this, cpu=ppc64le can
be normalized to ppc64 also in configure and not just in the meson
cross file.

bbbd9b6ec6 tests/acceptance: rename tests acceptance to tests avocado
In the discussion about renaming the `tests/acceptance` [1], the
conclusion was that the folders inside `tests` are related to the
framework running the tests and not directly related to the type of
the tests.

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the
CI related files and the documentation.

de38c0cc79 configure: ignore preexisting QEMU_*FLAGS envvars
User flags should be passed via CFLAGS/CXXFLAGS/LDFLAGS,
or --extra-cflags/extra-cxxflags/--extra-ldflags on the
command line.

QEMU_CFLAGS, QEMU_CXXFLAGS and QEMU_LDFLAGS are reserved
for flags detected by configure, so do not add to them
and clear them at the beginning of the script.

a286666044 configure: propagate --extra-cflags and --extra-ldflags to meson compile tests
Meson (intentionally) does not add QEMU_CFLAGS to cc.compiles/cc.links
tests, as they are supposed to be independent of the specific sets of
compilation flags used to build the programs.  However, the user can
still use CFLAGS or the toolchain file's LANG_args/LANG_link_args option
to specify -I or -L options that apply to cc.compiles/cc.links as well.

This is also the intended use of configure's --extra-cflags,
--extra-cxxflags and --extra-ldflags options.  For example, if
one has netmap's header in a nonstandard directory, up to commit
837b84b1c0 it used to work fine to do:

.../configure --enable-netmap \
     --extra-cflags=-I/path/to/netmap/sys

but since the test was converted to meson, this does not work anymore.

Pass these options to meson via the toolchain file instead of via
config-host.mak, since both have the same purpose.

6638cae5f6 meson: bump submodule to 0.59.3
This gains some bugfixes, especially:

- it fixes the introspection of array options.  While technically we
still support Meson 0.58.2, this issue only appears when adding a new
option and not if the user is just building QEMU.  In the relatively
rare case of a contributor using --meson to point to a 0.58 version,
review can catch spurious changes to scripts/meson-buildoptions.sh
easily.

- it fixes "meson test" when it is not the process group leader.  Make is
the process group leader when "make check" invokes "meson test", so this
is a requirement for using it as a test harness.

ffd205ef29 Partially revert "build: -no-pie is no functional linker flag"
This partially reverts commit bbd2d5a812.

This commit was misguided and broke using --disable-pie on any distro
that enables PIE by default in their compiler driver, including Debian
and its derivatives. Whilst -no-pie is not a linker flag, it is a
compiler driver flag that ensures -pie is not automatically passed by it
to the linker. Without it, all compile_prog checks will fail as any code
built with the explicit -fno-pie will fail to link with the implicit
default -pie due to trying to use position-dependent relocations. The
only bug that needed fixing was LDFLAGS_NOPIE being used as a flag for
the linker itself in pc-bios/optionrom/Makefile.

Note this does not reinstate exporting LDFLAGS_NOPIE, as it is unused,
since the only previous use was the one that should not have existed. I
have also updated the comment for the -fno-pie and -no-pie checks to
reflect what they're actually needed for.

3b4da13293 configure: automatically parse command line for meson -D options
Right now meson_options.txt lists about 90 options.  Each option
needs code in configure to parse it and pass the option down to Meson as
a -D command-line argument; in addition the default must be duplicated
between configure and meson_options.txt.  This series tries to remove
the code duplication by generating the case statement for those --enable
and --disable options, as well as the corresponding help text.

About 80% of the options can be handled completely by the new mechanism.
Eight meson options are not of the --enable/--disable kind.  Six more need
to be parsed in configure for various reasons documented in the patch,
but they still have their help automatically generated.

The advantages are:

- less code in configure

- parsing and help is more consistent (for example --enable-blobs was
  not supported)

- options are described entirely in one place, meson_options.txt.
  This make it more attractive to use Meson options instead of
  hand-crafted configure options and config-host.mak

A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends.  However, the old names are allowed
for backwards compatibility.

Prepare the configure script and Makefile for automatically generated
help and parsing.

Because we need to run the script to generate the full help, we
cannot rely on the user supplying the path to a Python interpreter
with --python; therefore, the introspection output is parsed into
shell functions and stored in scripts/.  The converter is written
in Python as standard for QEMU, and this commit contains a stub.

There are not many cases you would want to do this but one is if you
want to use a test friendly compiler like gcc instead of a system
compiler like clang. Either way we should honour the users choice if
they have made it.

654d6b0453 meson: switch minimum meson version to 0.58.2, minimum recommended to 0.59.2
Meson 0.58.2 does not need b_staticpic=$pie anymore, and has
stabilized the keyval module.  Remove the workaround and use a few
replacements for features deprecated in the 0.57.0 release cycle.

One feature that we would like to use is passing dependencies to
summary.  However, that was broken in 0.59.0 and 0.59.1.  Therefore,
use the embedded Meson if the host has anything older than 0.59.2,
but allow --meson= to use 0.58.2.

4dba278908 configure, meson: move CPU_CFLAGS out of QEMU_CFLAGS
Flags that choose the target architecture, such as -m32 on x86, affect
all invocations of the compiler driver, for example including options
such as --print-search-dirs.  To ensure that they are treated as such,
place them in the cross file in the [binaries] section instead of
including them in QEMU_CFLAGS.

3830df5f83 configure: Loosen GCC requirement from 7.5.0 to 7.4.0
As discussed in issue 614, we're shipping GCC 7.4.0 as the
system compiler in NetBSD 9, the most recent stable branch,
and are still actively interested in QEMU on this platform.

The differences between GCC 7.5.0 and 7.4.0 are trivial.

The GBM library detection does not need to be in the configure script,
since it does not have any user-facing options (there are no
--enable-gbm or --disable-gbm switches). Let's move it to meson.build
instead, so we don't have to clutter config-host.mak with the related

Additionally, only check for GBM if it is really required, i.e. if we
either compile with OpenGL or with virglrenderer support.

b906acace2 plugins: do not limit exported symbols if modules are active
On Mac --enable-modules and --enable-plugins are currently incompatible, because the
Apple -Wl,-exported_symbols_list command line options prevents the export of any
symbols needed by the modules.  On x86 -Wl,--dynamic-list does not have this effect,
but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides
it.  On Apple there is no -Wl,--export-dynamic, because it is the default, and thus
no override.

Either way, when modules are active there is no reason to include the plugin_ldflags.
While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is
specified but --enable-modules is not; this way, the GNU and Apple configurations
are more similar.

dfc86c0f25 fuzz: add an instrumentation filter
By default, -fsanitize=fuzzer instruments all code with coverage
information. However, this means that libfuzzer will track coverage over
hundreds of source files that are unrelated to virtual-devices. This
means that libfuzzer will optimize inputs for coverage observed in timer
code, memory APIs etc. This slows down the fuzzer and stores many inputs
that are not relevant to the actual virtual-devices.

With this change, clang versions that support the
"-fsanitize-coverage-allowlist" will only instrument a subset of the
compiled code, that is directly related to virtual-devices.

5b945f23d6 configure: Add -Werror to avx2, avx512 tests
When using clang, we get

ERROR: configure test passed without -Werror but failed with -Werror.
       This is probably a bug in the configure script. The failing command
       will be at the bottom of config.log.
       You can run configure with --disable-werror to bypass this check.

What we really want from these two tests is whether the
entire code sequence is supported, including pragmas.
Adding -Werror makes the test properly fail for clang.

e5f05f8c37 block: Add option to use driver whitelist even in tools
Currently, the block driver whitelists are only applied for the system
emulator. All other binaries still give unrestricted access to all block
drivers. There are use cases where this made sense because the main
concern was avoiding customers running VMs on less optimised block
drivers and getting bad performance. Allowing the same image format e.g.
as a target for 'qemu-img convert' is not a problem then.

However, if the concern is the supportability of the driver in general,
either in full or when used read-write, not applying the list driver
whitelist in tools doesn't help - especially since qemu-nbd and
qemu-storage-daemon now give access to more or less the same operations
in block drivers as running a system emulator.

In order to address this, introduce a new configure option that enforces
the driver whitelist in all binaries.

659eb157a5 configure: Fix endianess test with LTO
If a user is trying to compile QEMU with link-time optimization
enabled by running the configure script like this:

 .../configure --extra-cflags="-flto"

then the endianess test is failing since the magic values do not
show up in the intermediate object files there. If the host is
a big endian machine (like s390x), the QEMU binary is then unusable
since the corresponding variable "bigendian" is pre-initialized
with "no".

To fix this issue, we should rather create a full binary and look
for the magic strings there instead.
And we really should not continue the build if the endianess check
failed, to make it clear right from the start that something went
wrong here, thus let's also add some "exit 1" statements here
after emitting the error message.

ba4dd2aabc tcg/plugins: enable by default for most TCG builds
Aside from a minor bloat to file size the ability to have TCG plugins
has no real impact on performance unless a plugin is actively loaded.
Even then the libempty.so plugin shows only a minor degradation in
performance caused by the extra book keeping the TCG has to do to keep
track of instructions. As it's a useful feature lets just enable it by
default and reduce our testing matrix a little.

We need to move our linker testing earlier so we can be sure we can
enable the loader module required. As we have ruled out static &
plugins in an earlier patch we can also reduce the indent a little.

bbe47ed292 trace, lttng: require .pc files
The next version of lttng-libs will not require liburcu at run time anymore.
Therefore, it is expected that distros will not include the urcubp libraries
anymore when installing lttng-ust-devel.

To avoid future problems, just require pkg-config to detect lttng-ust.
The .pc files for lttng-ust correctly include liburcubp.a for static
builds, and have always done since pkg-config files were added in 2011.

d1d5e9eefd configure: allow the selection of alternate config in the build
While the default config works well enough it does end up enabling a
lot of stuff. For more minimal builds we can select a different list
of devices and let Kconfig work out what we want. For example:

  ../../configure --without-default-features \
    --target-list=arm-softmmu,aarch64-softmmu \
    --with-devices-aarch64=minimal

will override the aarch64-softmmu default set of devices with a more
minimal set of devices that just enables the virt and sbsa-ref models.

63a7f85306 meson: fix missing preprocessor symbols
While most libraries do not need a CONFIG_* symbol because the
"when:" clauses are enough, some do.  Add them back or stop
using them if possible.

In the case of libpmem, the statement to add the CONFIG_* symbol
was still in configure, but could not be triggered because it
checked for "no" instead of "disabled" (and it would be wrong anyway
since the test for the library has not been done yet).

3af448b386 configure: Check whether we can compile the s390-ccw bios with -msoft-float
The -msoft-float switch is not available in older versions of Clang.
Since we rely on the compiler to not generate floating point instructions
unexpectedly, we block those old compilers now via a test in the configure
script. Note that for some weird reasons, the Clang compiler only complains
about the missing soft-float support if no other flags are passed via
"-Wl,..." to the linker. So we have to use "compile_object" instead of
"compile_prog" for this check.

96ff758c6e linux-user: Use public sigev_notify_thread_id member if available
_sigev_un._tid is an internal glibc field and is not available on
musl libc. The sigevent(7) man page and Linux UAPI headers both use
sigev_notify_thread_id as a public way to access this field.

musl libc supports this field since 1.2.2[0], and glibc plans to
add support as well[1][2].

If sigev_notify_thread_id is not available, fall back to _sigev_un._tid
as before.

b4c6036faa configure: bump min required glib version to 2.56
The glib version was not previously constrained by RHEL-7 since it
rebases fairly often. Instead SLES 12 and Ubuntu 16.04 were the
constraints in 00f2cfbbec. Both of
these are old enough that they are outside our platform support
matrix now.

Per repology, current shipping versions are:

             RHEL-8: 2.56.4
      Debian Buster: 2.58.3
 openSUSE Leap 15.2: 2.62.6
   Ubuntu LTS 18.04: 2.56.4
   Ubuntu LTS 20.04: 2.64.6
            FreeBSD: 2.66.7
          Fedora 33: 2.66.8
          Fedora 34: 2.68.1
            OpenBSD: 2.68.1
     macOS HomeBrew: 2.68.1

Thus Ubuntu LTS 18.04 / RHEL-8 are the constraint for GLib version
at 2.56

b4c10fc6fe block/ssh: Bump minimum libssh version to 0.8.7
It has been over two years since RHEL-8 was released, and thus per the
platform build policy, we no longer need to support RHEL-7 as a build
target. So from the RHEL-7 perspective, we do not have to support
libssh v0.7 anymore now.

Let's look at the versions from other distributions and operating
systems - according to repology.org, current shipping versions are:

             RHEL-8: 0.9.4
      Debian Buster: 0.8.7
 openSUSE Leap 15.2: 0.8.7
   Ubuntu LTS 18.04: 0.8.0 *
   Ubuntu LTS 20.04: 0.9.3
            FreeBSD: 0.9.5
          Fedora 33: 0.9.5
          Fedora 34: 0.9.5
            OpenBSD: 0.9.5
     macOS HomeBrew: 0.9.5
         HaikuPorts: 0.9.5

* The version of libssh in Ubuntu 18.04 claims to be 0.8.0 from the
name of the package, but in reality it is a 0.7 patched up as a
Frankenstein monster with patches from the 0.8 development branch.
This gave us some headaches in the past already and so it never worked
with QEMU. All attempts to get it supported have failed in the past,
patches for QEMU have never been merged and a request to Ubuntu to
fix it in their 18.04 distro has been ignored:

 https://bugs.launchpad.net/ubuntu/+source/libssh/+bug/1847514

Thus we really should ignore the libssh in Ubuntu 18.04 in QEMU, too.

Fix it by bumping the minimum libssh version to something that is
greater than 0.8.0 now. Debian Buster and openSUSE Leap have the
oldest version and so 0.8.7 is the new minimum.

Fix it by checking whether any of these files are available before

e0447a834d configure: Poison all current target-specific #defines
We are generating a lot of target-specific defines in the *-config-devices.h
and *-config-target.h files. Using them in common code is wrong and leads
to very subtle bugs since a "#ifdef CONFIG_SOMETHING" is not working there
as expected. To avoid these issues, we are already poisoning many of the
macros in include/exec/poison.h - but it's cumbersome to maintain this
list manually. Thus let's generate an additional list of poisoned macros
automatically from the current config switches - this should give us a
much better test coverage via the different CI configurations.

Note that CONFIG_TCG (which is also defined in config-host.h) and
CONFIG_USER_ONLY are special, so we have to filter these out.

5ecfb76ccc configure: fix detection of gdbus-codegen
"pkg-config --variable=gdbus_codegen gio-2.0" returns "gdbus-codegen",
and it does not pass test -x (which does not walk the path).

Meson 0.58.0 notices that something is iffy, as the dbus_vmstate1
assignment in tests/qtest/meson.build uses an empty string as the
command, and fails very eloquently:

../tests/qtest/meson.build:92:2: ERROR: No program name specified.

Use the "has" function instead of test -x, and fix the generation
of config-host.mak since meson.build expects that GDBUS_CODEGEN
is absent, rather than empty, if the tool is unavailable.

a5b2afd522 pc-bios/s390-ccw: Allow building with Clang, too
Clang unfortunately does not support generating code for the z900
architecture level and starts with the z10 instead. Thus to be able
to support compiling with Clang, we have to check for the supported
compiler flags. The disadvantage is of course that the bios image
will only run with z10 guest CPUs upwards (which is what most people
use anyway), so just in case let's also emit a warning in that case
(we will continue to ship firmware images that have been pre-built
with GCC in future releases, so this should not impact normal users,
too).

Usually Meson uses pre-serialized information in meson-private to
speed up re-runs.  This is not possible for version changes, where
Meson instead rebuilds the serialized information using cmd_line.txt.
In some cases cmd_line.txt can contain stale information, since it
is not rebuild except when "meson setup" is invoked.  Update it in
the configure script to allow upgrading our Meson version.

c7328271cf configure: Do not use default_feature for EXESUF
Commit "c87ea11631 configure: add --without-default-features" use
default_feature to set default values for configure option. This value
is used for EXESUF too.

However, EXESUF is not option to be tested, it is just append to any
binary name so using --without-default-features set EXESUF to "n"o and
all binaries using it has form <name>no (e.g. qemu-imgno).

This is not expected behavior as disabling features should not cause
generating different binary names.

Reverting back to setting EXESUF to empty value unless needed otherwise.

44b99a6d5f exec: Build page-vary-common.c with -fno-lto
In bbc17caf81, we used an alias attribute to allow target_page
to be declared const, and yet be initialized late.

This fails when using LTO with several versions of gcc.
The compiler looks through the alias and decides that the const
variable is statically initialized to zero, then propagates that
zero to many uses of the variable.

This can be avoided by compiling one object file with -fno-lto.
In this way, any initializer cannot be seen, and the constant
propagation does not occur.

Since we are certain to have this separate compilation unit, we
can drop the alias attribute as well.  We simply have differing
declarations for target_page in different compilation units.
Drop the use of init_target_page, and drop the configure detection
for CONFIG_ATTRIBUTE_ALIAS.

In order to change the compilation flags for a file with meson,
we must use a static_library.  This runs into specific_ss, where
we would need to create many static_library instances.

Fix this by splitting page-vary.c: the page-vary-common.c part is
compiled once as a static_library, while the page-vary.c part is
left in specific_ss in order to handle the target-specific value
of TARGET_PAGE_BITS_MIN.

bc6a3565c8 configure: Improve OpenGL dependency detections
This has the following visible changes:

- GBM is required only for OpenGL dma-buf.
- X11 is explicitly required by gtk-egl.
- EGL is now mandatory for the OpenGL displays.

The last one needs some detailed description. Before this change,
EGL was tested only for OpenGL dma-buf with the check of
EGL_MESA_image_dma_buf_export. However, all of the OpenGL
displays depend on EGL and EGL_MESA_image_dma_buf_export is always
defined by epoxy's EGL interface.
Therefore, it makes more sense to always check the presence of EGL

efce01bcb6 configure: fix --enable-fuzzing linker failures
With --enable-fuzzing, QEMU_CFLAGS include -fsanitize=fuzzer-no-link.
This should allow us to build non-fuzzer binaries using objects
instrumented for fuzzing. However, to do that, we also need to link with
-fsanitize=fuzzer-no-link. We were not doing that.

For SVE, currently the bulk of the GDB TCG tests, we need at least GDB
9.1 to support the "ieee_half" data type we report. This only affects
when GDB tests are run; users can still use lower versions of gdb as
long as they aren't talking to an SVE enabled model. The work around
is to either get a newer gdb or disable SVE for their CPU model.

7d7dbf9dc1 configure: replace --enable/disable-git-update with --with-git-submodules
Replace the --enable-git-update and --disable-git-update configure params
with the param --with-git-submodules=(update|validate|ignore) to
allow 3 options for building from a git repo.

This is needed because downstream packagers, e.g. Debian, Ubuntu, etc,
also keep the source code in git, but do not want to enable the
'git_update' mode; with the current code, that's not possible even
if the downstream package specifies --disable-git-update.

The previous parameters are deprecated but still available; the
--enable-git-update parameter maps to --with-git-submodules=update and
--disable-git-update parameter maps to --with-git-submodules=validate.

The configure script behavior is slightly modified, where previously
the dtc, capstone, and slirp submodules were not validated when
--disable-git-update was specified (but were updated with git-update
enabled), now they are validated when using --with-git-submodules=validate
and are only ignored when using --with-git-submodules=ignore.

32063086a7 darwin: remove 64-bit build detection on 32-bit OS
A workaround added in early days of 64-bit OSX forced x86_64 if the
host machine had 64-bit support. This creates issues when cross-
compiling for ARM64. Additionally, the user can always use --cpu=* to
manually set the host CPU and therefore this workaround should be
removed.

2b9f74efcc configure: Move preadv check to meson.build
Move the preadv availability check to meson.build.  This is what we
want to be doing for host-OS-feature-checks anyway, but it also fixes
a problem with building for macOS with the most recent XCode SDK on a
Catalina host.

On that configuration, 'preadv()' is provided as a weak symbol, so
that programs can be built with optional support for it and make a
runtime availability check to see whether the preadv() they have is a
working one or one which they must not call because it will
runtime-assert.  QEMU's configure test passes (unless you're building
with --enable-werror) because the test program using preadv()
compiles, but then QEMU crashes at runtime when preadv() is called,
with errors like:

  dyld: lazy symbol binding failed: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

  dyld: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

Meson's own function availability check has a special case for macOS
which adds '-Wl,-no_weak_imports' to the compiler flags, which forces
the test to require the real function, not the macOS-version-too-old
stub.

So this commit fixes the bug where macOS builds on Catalina currently
require --disable-werror.

15588a6245 configure: MinGW respect --bindir argument
There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
 1) A standalone distribution, where QEMU is self contained and
    extracted by the user, such as a user would download from the QEMU
    website. In this case, all the QEMU executable files should be
    rooted in $prefix to ensure they can be easily found by the user
 2) QEMU integrated into a distribution image/sysroot/SDK and
    distributed with other programs. In this case, the provided
    arguments for bindir/datadir/etc. should be respected as they for a
    Linux build.

Restructures the MinGW path configuration so that all of the paths
except bindir use the same rules as when building for other platforms.
This satisfies #2 and #1 since these files do not need to be directly in
$prefix anyway.

The handling for --bindir is changed so that it defaults to $prefix on
MinGW (maintaining the compatibility with #1), but if the user specifies
a specific path when configuring it can also satisfy #2.
