Since this would be a native compiler, I suppose it wouldn't be
prefixed with the target name. You'd probably have to configure
--program-prefix=sparc64-linux-

To the best of my knowledge, the most stable sparc64-compatible
compiler ever made publicly available is the one that came with the
latest release of Red Hat Linux for sparc. That's because (as far as
I understand it, but don't take my word for it :-) that version had
the subreg_byte patch, without which there's just no way for GCC to
generate correct code for sparc64. This patch was recently merged in
the GCC CVS tree, so the latest development snapshot of GCC may just
work (hmm, probably not; development snapshots have been coming out of
the 3.0 branch, but IIRC the patch is only in mainline). Another
alternative is the GCC version available at rawhide.redhat.com.
