[SPARC64]: Add -mtune=ultrasparc3 if possible.
This gives better heuristics for the cost of a multiply (fixed
5 cycles), rather than the 'ultrasparc' setting (variable, and
unpredictable if the second argument is non-constant).
Example code size savings:
text data bss dec hex filename
3823690 304040 448880 4576610 45d562 vmlinux
3824521 304040 448880 4577441 45d8a1 vmlinux.orig
