xcompile: Remove --rtlib switch from clang CFLAGS

Fix the following error from clang invoking gcc linker with wrong arg:

i386-elf-gcc: error: unrecognized command line option '--rtlib=libgcc';
did you mean '-static-libgcc'?
clang-4.0: error: linker (via gcc) command failed with exit code 1

Just remove --rtlib switch from CFLAGS relating to clang
