At the moment, we look for just "python3" and "python", which is good
enough almost all of the time. But ... if you are on a platform that
uses an older Python by default and only offers a newer Python as an
option, you'll have to specify --python=/usr/bin/foo every time.
We can be kind and instead make a cursory attempt to locate a suitable
Python binary ourselves, looking for the remaining well-known binaries.
This configure loop will prefer, in order:
1. Whatever is specified in $PYTHON
2. python3
3. python
4. python3.11 down through python3.6
Notes:
- Python virtual environment provides binaries for "python3", "python",
and whichever version you used to create the venv,
e.g. "python3.8". If configure is invoked from inside of a venv, this
configure loop will not "break out" of that venv unless that venv is
created using an explicitly non-suitable version of Python that we
cannot use.
- In the event that no suitable python is found, the first python found
is the version used to generate the human-readable error message.
- The error message isn't printed right away to allow later
configuration code to pick up an explicitly configured python.

If neither --python nor --meson are specified, Meson's generated
build.ninja will invoke Python script using the interpreter *that Meson
itself is running under*; not the one identified by configure.
This is only an issue if Meson's Python interpreter is not "the first
one in the path", which is the one that is used if --python is not
specified. A common case where this happen is when the "python3" binary
comes from a virtual environment but Meson is not installed (with pip)
in the virtual environment. In this case (presumably) whoever set up
the venv wanted to use the venv's Python interpreter to build QEMU,
while Meson might use a different one, for example an enterprise
distro's older runtime.
So, detect whether a virtual environment is setup, and if the virtual
environment does not have Meson, use the meson submodule. Meson will
then run under the virtual environment's Python interpreter.

Anthony Perard recently reported some problems with Clang v6.0 from
Ubuntu Bionic (with regards to the -Wmissing-braces configure test).
Since we're not officially supporting that version of Ubuntu anymore,
we should better bump our minimum version check in the configure script
instead of using our time to fix problems of unsupported compilers.
According to repology.org, our supported distros ship these versions
of Clang (looking at the highest version only):
Fedora 36: 14.0.5
CentOS 8 (RHEL-8): 12.0.1
Debian 11: 13.0.1
OpenSUSE Leap 15.4: 13.0.1
Ubuntu LTS 20.04: 12.0.0
FreeBSD Ports: 15.0.7
NetBSD pkgsrc: 15.0.7
Homebrew: 15.0.7
MSYS2 mingw: 15.0.7
Haiku ports: 12.0.1
While it seems like we could update to v12.0.0 from that point of view,
the default version on Ubuntu 20.04 is still v10.0, and we use that for
our CI tests based via the tests/docker/dockerfiles/ubuntu2004.docker
file.
Thus let's make v10.0 our minimum version now (which corresponds to
Apple Clang version v12.0). The -Wmissing-braces check can then be
removed, too, since both our minimum GCC and our minimum Clang version
now handle this correctly.

We've been very gradually adding G_GNUC_PRINTF annotations
to functions over years. This has been useful in detecting
certain malformed printf strings, or cases where we pass
user data as the printf format which is a potential security
flaw.
Given the inherant memory corruption danger in use of format
strings vs mis-matched variadic arguments, it is worth applying
G_GNUC_PRINTF to all functions using printf, even if we know
they are safe.
The compilers can reasonably reliably identify such places
with the -Wsuggest-attribute=format / -Wmissing-format-attribute
flags.

running `make check-tcg` just prints the following:
```
make: Nothing to be done for 'check-tcg'

In the probe_target_compiler function, the 'break'
command is used incorrectly. There are no lexically
enclosing loops associated with that break command which
is an unspecfied behaviour in the POSIX standard.
The dash shell implementation aborts the currently executing
loop, in this case, causing the rest of the logic for the loop
in line 2490 to be skipped, which means no Makefiles are
generated for the tcg target tests.

When determining the endiandness of the target architecture we're
building for a small program is compiled, which in an obfuscated
way declares two strings. Then, we look which string is in
correct order (using strings binary) and deduct the endiandness.
But using the strings binary is problematic, because it's part of
toolchain (strings is just a symlink to
x86_64-pc-linux-gnu-strings or llvm-strings). And when
(cross-)compiling, it requires users to set the symlink to the
correct toolchain.
Fortunately, we have a better alternative anyways. We can mimic
what compiler.h is already doing: comparing __BYTE_ORDER__
against values for little/big endiandness.

s390-ccw remains a bit more complex, because the -march=z900 test is done
only for the native cross compiler. Otherwise, all that is needed is
to pass the (now mandatory) target argument to write_target_makefile.

Remove the symlink to tests/tcg/config-*.mak, which is possible now
that unused target config files are not created either.

It will not be specific to tests/tcg anymore, since it will be possible to
build firmware using container-based cross compilers too.

Further decoupling of tests/tcg from the main QEMU Makefile, and making
the build more similar between the cross compiler case and the vetted
container images.

Instead of linking tests/tcg/Makefile.target into the build tree, name
the symbolic link "Makefile" and create it in every target subdirectory.
This makes it possible to just invoke "make" in tests/tcg subdirectories.

Remove the DOCKER_SCRIPT and TARGET variable from the Makefile invocation
for tests/tcg. For DOCKER_SCRIPT, resolve the path to docker.py in configure;
for TARGET, move it to config-$(TARGET).mak and use a symbolic link to break
the cycle.
The symbolic link is still needed because tests/tcg includes dummy config files
for targets that are not buildable. Once that is cleaned up, the symbolic link
will go away too.

The test is slightly weaker than before, because it does not
call an extern "C" function from a C source file. However,
in practice what we seek to detect is ABI compatibility of the
various sanitizer flags, and for that it is enough to compile
anything with CC and link it with CXX.

This removes the dependency of dbus-display on --enable-modules. It also allows
cleanups in modinfo collection and allows moving C++ compiler detection to
meson.build.
Because it is now deprecated to use install_subdir to create an empty directory,
replace it with install_emptydir.
Updating the Meson submodule to 0.61.5 also removes the message
WARNING: Broken python installation detected. Python files installed
by Meson might not be found by python interpreter.
unless using system meson is forced with --meson.

Just use using the compiler binary, with -nostdlib in the case of the
linker; the compiler driver (whether i686-*-gcc, or x86_64-*-gcc with
the -m32 option) will then pick the right magic option to as and ld.
