As far as I can tell, gcc 4.x has no --with-cpu option. We pass the correct march and mtune options to the compiler at runtime through CFLAGS and friends. You're already found the way to pass configuration to *libc using values in TARGET_FPU to pickup the right configuration. Is there a use case we're missing?
