You can't build llvm-gcc like that. There's a build_gcc script (in
the root of the llvm-gcc source) that does a proper build the way that
Apple does it. No idea if it will work as-is on Linux, but you should
start there. See also README.LLVM (in the same place), although there
are some extra complications in the build_gcc script because of the
