I think this is what all your questions come down to.  Solaris does
not have separate distributions for 32-bit and 64-bit; there's only
one DVD, and AFAIK the installations it produces when run on 32-bit
and 64-bit hardware are identical except for the kernel.  Now what Sun
could do, given this, is to distribute both a 32-bit gcc that produces
32-bit objects by default, and a 64-bit gcc that produces 64-bit
objects by default, put them in different bin directories, and let you
use $PATH to select the one you want.  But they haven't done that.

As for why x86_64-pc-solaris2 doesn't work as a GCC target, I think
the answer is simply that no one has gotten around to making it work.
I'm sure the GCC team would be happy to receive a patch for this.  I
don't think I have time to produce one anytime soon, though.
