src/lib/Makefile.inc: Allow rmodules to link under Clang 

rmodules were getting linked with libgcc and not libcompiler-rt.
Unfortunately this is pretty ugly however we do this else where
in the build system so its consistently ugly. The build system
will later need a unification pass between compilers once we are
tree stable on Clang.
