Hi all,

I'm working on a zig-build-system and I have something working.

I'd like to discuss some of the problems I found because I don't
know what's the best solution:

- I don't know how to configure the cross-compilation
- The `zig` command uses a compiler to find the libc it needs to use
  we should be able to remove the `gcc-toolchain` from the
  dependencies if we just add the libc to the build system properly
  (this point is mixed with the point above)

I need suggestions on these...

I attach two patches, one for the current build system I made and
a second one for an example package that actually works but has
some weird needs you can find in the comments.

Cheers,
Ekaitz
