Our Makefile massages the given make arguments to invoke ninja
accordingly. One key difference is that ninja will parallelize by
default, whereas make only does so with -j<n> or -j. The make man page
says that "if the -j option is given without an argument, make will not
limit the number of jobs that can run simultaneously". We use to support
that by replacing -j with "" (empty string) when calling ninja, so that
it would do its auto-parallelization based on the number of CPU cores.
This was accidentally broken at d1ce2cc95b (Makefile: preserve
--jobserver-auth argument when calling ninja, 2024-04-02),
causing `make -j` to fail:
$ make -j V=1
/usr/bin/ninja -v -j -d keepdepfile all | cat
make -C contrib/plugins/ V="1" TARGET_DIR="contrib/plugins/" all
ninja: fatal: invalid -j parameter
make: *** [Makefile:161: run-ninja] Error
Let's fix that and indent the touched code for better readability.

Qemu wraps its call to ninja in a Makefile. Since ninja, as opposed to
make, utilizes all CPU cores by default, the qemu Makefile translates
the absense of a `-jN` argument into `-j1`. This breaks jobserver
functionality, so update the -jN mangling to take the --jobserver-auth
argument into considerationa too.

This is not ideal, since it requires all cross-compilers
to be present rather than a simple subset. But since it
is only run manually, should be good enough for now.

Stop applying config-host.mak to the sourcesets, since it does not

In commit b0fcc6fc7f ("build: rebuild build.ninja using
"meson setup --reconfigure"", 2023-05-19) I changed the build.ninja
rule in the Makefile to use "meson setup" so that the Makefile would
pick up a changed path to the meson binary.
However, there was a reason why build.ninja was rebuilt using $(NINJA)
itself. Namely, ninja has its own cache of file modification times,
and if it does not know about the modification that was done outside
its control, it will *also* try to regenerate build.ninja. This can be
simply by running "make" on a fresh tree immediately after "configure";
that will trigger an unnecessary meson run.
So, apply a refinement to the rule in order to cover both cases:
- track the meson binary that was used (and that is embedded in
build.ninja's reconfigure rules); to do this, write build.ninja.stamp
right after executing meson successfully
- if it changed, force usage of "$(MESON) setup --reconfigure" to
update the path in the reconfigure rule
- if it didn't change, use "$(NINJA) build.ninja" just like before
commit b0fcc6fc7f.

The scenario for which --with-git= was introduced was to use a SOCKS proxy
such as tsocks. However, this was back in 2017 when QEMU's submodules
used the git:// protocol, and it is not as important when using the
"smart HTTP" backend; for example, neither "meson subprojects download"
nor scripts/checkpatch.pl obey the GIT environment variable.
So remove the knob, but test for the presence of git in the configure and
git-submodule.sh scripts, and suggest using --with-git-submodules=validate
+ a manual invocation of git-submodule.sh when git does not work. Hopefully
in the future the GIT environment variable will be supported by Meson.

Do not use the rule in build.ninja, because the path to meson is hardcoded
in build.ninja and this breaks if meson moves (for example if the distro
meson suddenly becomes too old after an update).

Run 'make distclean' in a tree, and GNUmakefile is removed.
But, GNUmakefile is where we change directory to build.
Run 'make distclean' or 'make clean' again, and Makefile applies
the clean actions, such as this one, at the top level of the tree.
For example, it removes the .d source files in 'meson/test cases/d/*/*.d'.
find . \( -name '*.so' -o -name '*.dll' -o \
-name '*.[oda]' -o -name '*.gcno' \) -type f \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-aarch64.a \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-arm.a \
-exec rm {} +
To fix, remove clean and distclean from UNCHECKED_GOALS, so those targets
are "checked", meaning that configure must be run before make. However,
the check action does not trigger, because clean does not depend on
config-host.mak, so change the action to simply throw an error.

Meson supports an "uninstall", so we can easily allow it to work by
not suppressing the forwarding of it from Make to meson.
We originally suppressed this because Meson's 'uninstall' has a hole
in it: it will remove everything that is installed by a mechanism
meson knows about, but not things installed by "custom install
scripts", and there is no "custom uninstall script" mechanism.
For QEMU, though, the only thing that was being installed by a custom
install script was the LC_MESSAGES files handled by Meson's i18n
module, and that code was fixed in Meson commit 487d45c1e5bfff0fbdb4,
which is present in Meson 0.60.0 and later. Since we already require
a Meson version newer than that, we're now safe to enable
'uninstall', as it will now correctly uninstall everything that was
installed.

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.
It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.
Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.
