Hi Paolo, I'm trying to get the QEMU CI run successfully for the
idef-parser patchset. However I'm facing an issue I haven't been able
to work around with meson. Maybe you can help?
The failing tests are cross-i386-*

I think the problem is that we're adding a new build-time dependency:
glib. However glib is also a run-time dependency and, AFAIU, when cross
compiling for x86 on a x86-64 machine, if you create a native
executable, meson picks up the x86 version of glib (as opposed to the
x86-64).
I've been fiddling with this for a while, unsuccessfully.
Relevant portion of the code:

Happy holidays!

Is the configure script setting $cross_compile to yes? That will decide
whether meson getting a --cross-file or a --native-file option, and
consequently whether it treats the host and build machines as equal or
different.

From what I can see cross_compile is set only if --cross-prefix is set,
which doesn't seem to be the case for most containers (e.g., s390x)
but not for i386:
tests/docker/dockerfiles/debian-s390x-cross.docker:ENV QEMU_CONFIGURE_OPTS --cross-prefix=s390x-linux-gnu-
tests/docker/dockerfiles/fedora-i386-cross.docker:ENV QEMU_CONFIGURE_OPTS --cpu=i386 --disable-vhost-user
I can try to set `--cross-prefix=x86_64-redhat-linux-` but I guess this
will prevent certain tests to run (given the cross-compile environment).
I'll give it a shot.
