bug#29644: gcc-objc is unusable without its 'gcc' executable

[Vivien Kraus]

Hello!

I would like to learn and play with gnustep with objective-C, but it
seems like GCC does not come with objective-C in Guix.

I don’t know much about GCC or how Guix packages it. There is an early
comment by Ricardo Wurmus:

The source of gcc-objc has a file named gcc-12.3.0/gcc/objc/lang-
specs.h that claims to be included as a static array literal, but I
don’t know what the rest of this citation means.
