        ./configure ABI=32 CC=cc CFLAGS="-xtarget=ultra -xO5"

CC=cc will be the default if that's the only compiler you've got, but
it never hurts to say exactly what you want.

Does -xtarget=ultra do something better than -xtarget=native?  If so
we could make put it into the default cflags for cc on ultrasparc-*-*.

Does cc support a "long long" in the 32-bit ABI, using 64-bit
registers for it (in function calls etc)?

Maybe we could think about having an ABI=32L or some such which would
be a 64-bit limb within the 32-bit ABI, as currently done for
powerpc64.
