05bfa963df configure: Fix error message when C compiler is not working
If you try to run the configure script on a system without a working
C compiler, you get a very misleading error message:

 ERROR: Unrecognized host OS (uname -s reports 'Linux')

Some people already opened bug tickets because of this problem:

 https://gitlab.com/qemu-project/qemu/-/issues/2057
 https://gitlab.com/qemu-project/qemu/-/issues/2288

We should rather tell the user that we were not able to use the C
compiler instead, otherwise they will have a hard time to figure
out what was going wrong.

While we're at it, let's also suppress the "unrecognized host CPU"
message in this case since it is rather misleading than helpful.

19a931f207 configure: quote -D options that are passed through to meson
Ensure that they go through unmodified, instead of removing one layer
of quoting.

-D is a pretty specialized option and most options that can have spaces
do not need it (for example, c_args is covered by --extra-cflags).
Therefore it's unlikely that this causes actual trouble.  However,
a somewhat realistic failure case would be with -Dpkg_config_path
and a pkg-config directory that contains spaces.

16f1f95ebd configure: run plugin TCG tests again
Commit 39fb3cfc28 ("configure: clean up plugin option handling", 2023-10-18)
dropped the CONFIG_PLUGIN line from tests/tcg/config-host.mak, due to confusion
caused by the shadowing of $config_host_mak.  However, TCG tests were still
expecting it.  Oops.

Put it back, in the meanwhile the shadowing is gone so it's clear that it goes
in the tests/tcg configuration.

eae7509be9 Revert "configure: run plugin TCG tests again"
This reverts commit 6eeeb87331.

This commit has been wrongly back-ported to 8.2.x, $config_host_mak
in master didn't include the tests/tcg/ prefix, while 8.2.0 did it.
The result of this "backport" is this message during configure:

 ../configure: 1679: cannot create tests/tcg/tests/tcg/config-host.mak: Directory nonexistent

Let's revert the change and try again.

bb28ee11c2 configure: use a native non-cross compiler for linux-user
Commit c2118e9e1a ("configure: don't try a "native" cross for linux-user",
2023-11-23) sought to avoid issues with using the native compiler with a
cross-endian or cross-bitness setup.  However, in doing so it ended up
requiring a cross compiler setup (and most likely a slow compiler setup)
even when building TCG tests that are native to the host architecture.
Always allow the host compiler in that case.

9abbb37535 configure: Make only once with pseudo-"in source tree" builds
Pseudo-"in source tree" build used to run make in the build directory
as many times as goals. Worse, although .NOTPARALLEL is specified,
it does not work for patterns, and run make in parallel, which can break
things.

Add a new rule "build", and let it call make. The pattern rule only
needs to specify "build" as its prerequisite and have a no-op recipe so
that it does more than canceling built-in implicit rules.

c2118e9e1a configure: don't try a "native" cross for linux-user
As 32 bit x86 become rarer we are starting to run into problems with
search paths. Although we switched to a Debian container we still
favour the native CC on a Bookworm host. As a result we have a broken
cross compile setup which then fails to build with:

    BUILD   i386-linux-user guest-tests
  In file included from /usr/include/linux/stat.h:5,
                   from /usr/include/bits/statx.h:31,
                   from /usr/include/sys/stat.h:465,
                   from /home/alex/lsrc/qemu.git/tests/tcg/multiarch/linux/linux-test.c:28:
  /usr/include/linux/types.h:5:10: fatal error: asm/types.h: No such file or directory
      5 | #include <asm/types.h>
        |          ^~~~~~~~~~~~~
  compilation terminated.
  make[1]: *** [Makefile:119: linux-test] Error 1
  make: *** [/home/alex/lsrc/qemu.git/tests/Makefile.include:50: build-tcg-tests-i386-linux-user] Error 2

This is likely to affect more and more linux-user builds so wrap the
whole check in a test for softmmu targets (aka bare metal) which don't
worry about such header niceties. This allows us to keep using the
host compiler for softmmu tests and the roms.

aa5730b07e tests/docker: replace fedora-i386 with debian-i686
Fedora is gradually killing off i386 packages in its repos, via a
death-by-1000-cuts process. Thus Debian looks like a better long
term bet for i686 build testing. It has the added advantage that
we can generate it via lcitool too.

528148980a configure: define "pkg-config" in addition to "pkgconfig"
Meson used to allow both "pkgconfig" and "pkg-config" entries in machine
files; the former was used for dependency lookup and the latter
was used as return value for "find_program('pkg-config')", which is a less
common use-case and one that QEMU does not need.

This inconsistency is going to be fixed by Meson 1.3, which will deprecate
"pkgconfig" in favor of "pkg-config" (the less common one, but it makes
sense because it matches the name of the binary). For backward
compatibility it is still allowed to define both, so do that in the
configure-generated machine file.

c691925092 tests/docker: make docker engine choice entirely configure driven
Since 0b1a649047 (tests/docker: use direct RUNC call to build
containers) we ended up with the potential for the remaining docker.py
script calls to deviate from the direct RUNC calls. Fix this by
dropping the use of ENGINE in the makefile and rely entirely on what
we detect at configure time.

We also tweak the RUNC detection so podman users can still run things
from the source tree.

ca056f4499 Python: Drop support for Python 3.7
Debian 10 is not anymore a supported distro, since Debian 12 was
released on June 10, 2023.  Our supported build platforms as of today
all support at least 3.8 (and all of them except for Ubuntu 20.04
support 3.9):

openSUSE Leap 15.5: 3.6.15 (3.11.2)
CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16, 3.11.4)
CentOS Stream 9:    3.9.17 (3.11.4)
Fedora 37:          3.11.4
Fedora 38:          3.11.4
Debian 11:          3.9.2
Debian 12:          3.11.2
Alpine 3.14, 3.15:  3.9.16
Alpine 3.16, 3.17:  3.10.10
Ubuntu 20.04 LTS:   3.8.10
Ubuntu 22.04 LTS:   3.10.12
NetBSD 9.3:         3.9.13*
FreeBSD 12.4:       3.9.16
FreeBSD 13.1:       3.9.18
OpenBSD 7.2:        3.9.17

Note: NetBSD does not appear to have a default meta-package, but offers
several options, the lowest of which is 3.7.15. However, "python39"
appears to be a pre-requisite to one of the other packages we request
in tests/vm/netbsd.

Since it is safe under our supported platform policy, bump our
minimum supported version of Python to 3.8.  The two most interesting
features to have by default include:

- the importlib.metadata module, whose lack is responsible for over 100
  lines of code in mkvenv.py

- improvements to asyncio, for example asyncio.CancelledError
  inherits from BaseException rather than Exception

In addition, code can now use the assignment operator ':='

Because mypy now learns about importlib.metadata, a small change to
mkvenv.py is needed to pass type checking.

73258b3864 configure, meson: remove CONFIG_SOLARIS from config-host.mak
CONFIG_SOLARIS is only used to pick tap implementations.  But the
target OS is invariant and does not depend on the configuration, so move
away from config_host and just use unconditional rules in softmmu_ss.

2c13c57441 configure, meson: move --enable-plugins to meson
While the option still needs to be parsed in the configure script
(it's needed by tests/tcg, and also to decide about recursing
into contrib/plugins), passing it to Meson can be done with -D
instead of using config-host.mak.

bafe78ad3b contrib/plugins: use an independent makefile
The initial reason to write this patch was to remove the last use of
CONFIG_DEBUG_TCG from the makefiles; the flags to use to build TCG
plugins are unrelated to --enable-debug-tcg, and instead they should
be the same as those used to build emulators (the plugins are not build
via meson for demonstration reasons only).

However, since contrib/plugins/Makefile is also the last case of doing
a compilation job using config-host.mak, go a step further and make it
use a completely separate configuration file, removing all references
to compilers from the toplevel config-host.mak.  Clean up references to
empty variables, and use .SECONDARY so that intermediate object files
are not deleted.

3c7ee49b81 configure: create native file with contents of $host_cc
The argument of --host-cc is not obeyed when cross compiling.  To avoid
this issue, place it in a configuration file and pass it to meson
with --native-file.

While at it, clarify that --host-cc is not obeyed anyway when _not_
cross compiling, because cc="$host_cc" is placed before --host-cc is
processed.
