And the reason for that magic choice is?
E.g. x86-64 has -fomit-frame-pointer by default, -funit-at-a-time
is also the default for -O2 and above.  Building all code PIC is a
de-optimization (although on x86-64 not a major one,the PIC cost is
not as high on x86-64 as on other arches), -O3 is for the vast majority
of code worse than -O2 as well.  -mtune=athlon64 is on by default too.

You'd need to hack up %configure macro etc.
