Neither gcc nor clang do anything more except calling the linker. The only component (in the whole clangbsd src tree) which still needs to be compiled with gcc is boot2, which otherwise ends up just a little too big, and doesn't fit. This is being worked on, but it isn't very critical, really. Note that clangbsd automatically uses gcc for this specific code, unless you override it manually.
