    [SPARC64]: Add -mtune=ultrasparc3 if possible. · 966d9056

    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
