In case of cross-compilation, GCC might provide its own linker. Its behaviour seems slightly different from that of gcc(1). This is not a big deal for normal situations, but the difference can cause libtool to go mad. We ship bundled libffi for windows users, and libffi uses libtool. If we use cross-compiler version of gcc instead of its ld conterpart, we fail to compile fiddle. That should not be what we want.
