[Buildroot] [PATCH 2/3] package/gobject-introspection: export cc in g-ir-scanner

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

Without this export, the host variant of g-ir-scanner will call the host
gcc for linking.

For autotools packages, this is not an issue as they use
Makefile.introspection, which will export the cross-cc, however for meson,
this is not the case, and linking errors occur when meson packages generate
.gir and .typelib files.
