Is your guix up to date?  Cross-compilation for 'glib-or-gtk' has been
implemented in:

commit 881a5d26b2fdf9ccb222b26b2a533cd09ffc62c8
Author: Maxime Devos <maximedevos@telenet.be>

    build-system/glib-or-gtk: Support cross-compilaton.
    
    * guix/build-system/glib-or-gtk.scm
      (lower): Add 'implicit-cross-inputs?' argument.  Generate a bag
      when cross-compiling.
      (glib-or-gtk-cross-build): New procedure.

Greetings,
Maxime.
