bug#50201: [PATCH core-updates-frozen 0/52] Support cross-compilation in glib-or-gtk-build-system and fix cross-compilation errors

[Mathieu Othacehe]

Hello,

I pushed the series, with a minor modification to add a reference to our
discussion on introspection data cross-compilation.

It would be nice to remove the associated TODOs on core-updates while
this is still fresh.

Thanks for your work on that topic,

Mathieu
