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?
Cheers,
Richard
