How about #:make-flags '("CC=gcc") instead?  That's what I did in:

http://git.savannah.gnu.org/cgit/guix.git/commit/?h=wip-network-manager&id=d83bc88067404d4005d6e84724901e34e3d218c9

Also, instead of replacing the 'configure' phase, how about patching
Makefile.linux in a new phase?  Our default 'configure' phase now does
things like passing --build to ensure a deterministic build triplet,
whereas on systems like ARM the guessed triplet depends on the build
machine.  So, it would be good to use the default 'configure' phase when
possible.

Otherwise looks good to me!

     Thanks,
