QEMU CI failure of cross-i386-* targets (meson picks wrong glib for native target)

[Alessandro Di Federico]

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!
