you do need the rest since darwin is unlikely to return the 64-bit

Actually, I was thinking about this. If you point CC=gcc64, then,
config.guess should return powerpc64. If you point it at a 32-bit
default, config.guess can return powerpc. I think this would be
safe, as very, very few people will have a 64 bit default compiler,
and those that do, want the next one to be as well.
You can notice this by compiling void *p = 0; and seeing it it is 32
or 64 bits.
I'd Ok that type of change, if anyone wants to do that.
