contrib: guix: More robust search paths, add checks

Browse source 
- store_path() previously only worked for cross compilation packages, we
  remove this assumption here
- Add CROSS_GCC_LIB variable which points to where gcc libs/headers are
  located
- Add gcc libs/headers to our CROSS_*_PATH environment variables
- Check that all directories in CROSS_*_PATH are sane
