commit: https://git.buildroot.net/buildroot/commit/?id=b5cd31429631113f7b50af12f06062060625d6c8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

We need to backport a commit to allow us to override the g-ir-scanner
and g-ir-compiler binaries in the gnome module.

By default since meson looks for these binaries as native: true
dependencies it would use the host versions instead of the wrappers
which are not useable for target package builds. Override this behavior
by specifying the correct wrapper binaries in cross-compilation.conf.

Fixes:

+This is useful when one needs to force meson to use wrappers for cross
