Configure is trying to fall back on cross compilers for targets that
can have bi-arch or bi-endian toolchains, but there are many corner
cases where just checking the name can go wrong. For example, the RHEL
ppc64le compiler is bi-arch and bi-endian, but multilibs are disabled.
Therefore it cannot be used to build 32-bit hosted binaries like the
linux-user TCG tests.
Trying the cross compiler first also does not work, and an example for
this is also ppc64le. The powerpc64-linux-gnu-gcc binary from the
cross-gcc package is theoretically multilib-friendly, but it cannot
find the CRT files on a ppc64le host, because they are not in the .../le
multilib subdirectory.
This can be fixed by testing both the native compiler and the cross
compiler, and proceeding with the first one that works. To do this,
move the compiler usability check from the tests/tcg snippet to inside
probe_target_compiler and, while at it, restrict the softmmu emulation
target to basically a test for the presence of libgcc.

tests/tcg/configure.sh has a complicated story.
In the beginning its code ran as part of the creation of config-target.mak
files, and that is where it placed the information on the target compiler.
However, probing for the buildability of TCG tests required multiple
inclusions of config-target.mak in the _main_ Makefile (not in
Makefile.target, which took care of building the QEMU executables in
the pre-Meson era), which polluted the namespace.
Thus, it was moved to a separate directory. It created small config-*.mak
files in $(BUILD_DIR)/tests/tcg. Those were also included multiple
times, but at least they were small and manageable; this was also an
important step in disentangling the TCG tests from Makefile.target.
Since then, Meson has allowed the configure script to go on a diet.
A few compilation tests survive (mostly for sanitizers) but these days
it mostly takes care of command line parsing, looking for tools, and
setting up the environment for Meson to do its stuff.
It's time to extend configure with the capability to build for more
than just one target: not just tests, but also firmware. As a first
step, integrate all the logic to find cross compilers in the configure
script, and move tests/tcg/configure.sh back there (though as a
separate loop, not integrated in the one that generates target
configurations for Meson).
tests/tcg is actually very close to being buildable as a standalone
project, so I actually expect the compiler tests to move back to
tests/tcg, as a "configure" script of sorts which would run at Make
time after the docker images are built. The GCC tree has a similar idea
of doing only bare-bones tree-wide configuration and leaving the rest
for Make time.

Our support statement for Windows currently talks about "Vista / Server
2008" - which is related to the API of Windows, and this is not easy
to understand for the non-technical users. Additionally, glib sets the
_WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API,
so QEMU effectively depends on the Windows 7 API, too.
Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as
glib uses and adjust our support statement in the documentation to
something similar that we're using for Linux and the *BSD systems
(i.e. only the two most recent versions), which should hopefully be
easier to understand for the users now.
And since we're nowadays also compile-testing QEMU with MSYS2 on Windows
itself, I think we could mention this build environment here, too.
