Based on my testing, if PKG_CONFIG_SYSROOT_DIR is set or not makes zero
difference on the outcome. I suspect this is related to how pkg-config is
launched by meson.
Looking at the meson source tree, in all ci/test cross compile scenarios
they reference a pkg-config wrapper. No cross compile scenario I see
referencing the 'pkgconfig' key uses a bare pkg-config.
cross/armclang-linux.txt:#pkgconfig =
'/usr/bin/arm-linux-gnueabihf-pkg-config'
cross/linux-mingw-w64-32bit.txt:pkgconfig =
'/usr/bin/i686-w64-mingw32-pkg-config'
cross/linux-mingw-w64-64bit.txt:pkgconfig =
'/usr/bin/x86_64-w64-mingw32-pkg-config'
cross/ubuntu-armhf.txt:pkgconfig =
'/usr/bin/arm-linux-gnueabihf-pkg-config'
test cases/unit/33 cross file overrides always
args/ubuntu-armhf-overrides.txt:pkgconfig =
'/usr/bin/arm-linux-gnueabihf-pkg-config'
test cases/unit/36 exe_wrapper behaviour/broken-cross.txt:pkgconfig =
'/usr/bin/x86_64-w64-mingw32-pkg-config'
I think adding a wrapper makes sense.
