How about passing the relevant options directly to gcc then ? I just re-read
the manual and there are plenty of variants in the new versions: i386, i486,
i586 (=pentium), i686 (=pentiumpro), k6, k6-2, k6-3, pentium-2, pentium-3,
pentium-4, athlon, athlon-xp, athlon-mp.
We could have --enable-optimizations=xxx for the -mcpu switch
and --enable-exclusive-optimizations=xxx for the -march switch, the default
being --enable-optimizations=pentium.
