Added -msupersparc for SUN4M-only configs, (right after -mv8) -msupersparc
supposedly adds additional instruction scheduling for better performance,
where -mv8 seems to only "allow" the multiply and div instructions. This
is what I got from the gcc docs anyway.. Reading the RTL for sparc seems
to agree with this hypothesis, and the man pages..
