On Solaris/SPARC, HiPE doesn't "want" gas. It just so happens that
many users have a pre-built gcc (supplied by Sun I presume) that's
been configured to use GNU as with Sun's ld, and that combo breaks
for unknown reasons on our code.

You don't see the problem because you have a different gcc, and the HiPE
group's gcc has been configured without --with-gnu-as to avoid the problem.

The problem will be debugged/fixed/worked-around as part of HiPE's SPARC
code rewrite scheduled to start in a couple of weeks. One way or another,
R12B won't have the problem.
