Does it say ultrasparct1-something now?
This isn't going to be sufficient to make the build work with the
compiler used (because of the addc breakage). I see two possibilities
for getting a 64-bit build:
1. Compile a real gcc and use that for building GMP.
2. Disable all machine dependent code, configuring with --host=none.
(I don't think we should spend a lot of work trying to make things run
faster on these machines. But we should try to make GMP work if we
can work around the addc breakage. I don't care for speeding up
things for a present day machine from 150x slower than the competition
to (say) a mere 50x slower. Sun customers that need radically better
GMP performance can complement their nifty T1 with a used PC. :-)
