Building target pkgconfig needs pkgconfig-native because pkgconfig uses
pkgconfig to find libglib. Inherit the pkgconfig class so that the
pkgconfig recipe does not need to know the details of how pkgconfig is
integrated.
Native builds use an internal copy of glib to avoid the circular
dependency, and the self-dependency on pkgconfig-native is automatically
pruned.

Perf uses pkg-config, so should inherit the class.
Also remove the sedding of PKG_CONFIG, we pass it in as an argument to
make via EXTRA_OEMAKE so the sed is redundant.

When Meson uses pkg-config to introspect the Python install it resets
PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR to the location that the running
python3 says is the library directory. However, when it writes to
PKG_CONFIG_LIBDIR it uses the _target_ library directory without
prefixing this with the sysroot, which breaks the build if _LIBDIR is
the primary search path.
This has been fixed in Meson since 1.10.0[1] but numpy has a vendored
fork of Meson that is currently at 1.9.2, so backport the specific fix
to solve this problem.

All recipes that use pkg-config should be inheriting the class so this
is a no-op change for those, and for recipes that do not use pkg-config
will no longer need to rebuild if these variables are changed.
Any recipes that use pkg-config but do not inherit the class will fail
to build, and this is intentional: those recipes should inherit the class.
This commit is simply the move of the exports, the values do not change.

Our PKG_CONFIG_* variables were a bit of a mess.
First, PKG_CONFIG_DIR is not used by either pkg-config or pkgconf. It's
set to (approximately) ${libdir}/pkgconfig but we also want to search
${datadir}/pkgconfig so it isn't actually useful as an intermediate
variable.
Remove PKG_CONFIG_DIR and replace with the neatest expression for the
value we want: ${STAGING_LIBDIR}/pkgconfig.
Second, PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR shouldn't be set to the
same paths. The semantics of these variables is that PKG_CONFIG_PATH is
searched first, followed by either PKG_CONFIG_LIBDIR or the default paths
compiled into the pkg-config binary.
Currently we set PKG_CONFIG_PATH to (approx.) ${libdir}:${datadir} and
PKG_CONFIG_LIBDIR to ${libdir}, so we search libdir twice.
Also the default paths embedded in the binary will be incorrect as they
point to pkgconfig-native's sysroot, so we absolutely need to set
PKG_CONFIG_LIBDIR.
Instead, set PKG_CONFIG_LIBDIR to ${libdir}:${datadir} so that the
default search path is correct. We can then leave PKG_CONFIG_PATH empty,
if a recipe has specific needs it can set that but normally it is not
needed anymore.
Then bubble these changes out to the few places where the variables are
used directly:
- Kernel/kconfig interaction where 'pkg-config' needs to read the
native files, not target.
- The class classes (native, etc) which redefine the values. However,
as the values are defined in terms of sysroot variables, we can
typically remove assignments from those classes as they are redundant.

Hi Ross,
This patch is almost fine on the autobuilder, with one little exception:
it breaks runtime_test.TestImage.test_testimage_virgl_gtk_sdl on some
hosts. Or to go further, when qemu-system-native is compiled with "gtk+"
PACKAGECONFIG, the it will have a dependency on host glib version and
might complain it is too old:
ERROR: qemu-system-native-10.2.0-r0 do_configure: Execution of '/srv/pokybuild/yocto-worker/oe-selftest-debian/build/build-st-2977320/tmp/work/x86_64-linux/qemu-system-native/10.2.0/temp/run.do_configure.845525' failed with exit code 1
...

https://autobuilder.yoctoproject.org/valkyrie/#/builders/35/builds/3105
This can be reproduced by either running
runtime_test.TestImage.test_testimage_virgl_gtk_sdl selftest, or just
building qemu-system-native with:
PACKAGECONFIG:append:pn-qemu-system-native = " gtk+"
Can you have a look at what is going wrong here?
Thanks,
Mathieu

There's no need to --with-pkg-confg-dir as the default is the same and
correct.
Don't append BBCLASSEXTEND, there's no need.
Sync pkg-config-native with the pkg-config recipe so that it sets
the variables in the same way.

The kernel has supported setting an alternative binary for pkg-config
with a variable since 5.19 (in 2022[1]) and we set that to
pkg-config-native, so there is no longer any need to also manually set
the PKG_CONFIG_* variables.
The relevant commit was backported and is present in 5.15.91 onwards,
but is not yet in 5.10.x.

Hit send and immediately remembered I forgot something:
I did a build of “world core-image-sato:do_populate_sdk” for master and with this series, and compared the deploy/ipk/ directories. The only changes were in meta-environment and the python build configuration, where PKG_CONFIG_PATH changes to PKG_CONFIG_LIBDIR.
