Can you summarize what is Qemu used for in the context of building
gobject-introspection ?

If it's to generate some architecture-specific file, can we
pre-generate it, and bundle it with Buildroot ?

I'd really like to avoid a qemu-based solution if possible. But of
course, if there's really no other option and people want
gobject-introspection, we won't have much choice :/

OK. Depending on what their autogen script is doing, you might be able
to fix it by using some kind of POST_PATCH_HOOKS. It really depends on
what the actual issue is.
