That's exactly what I thought was happening. I remembered that the
architecture is determined from the binary, so I assumed that my
executable was built as a sparcv9 but it was linking in a sparcv9a
shared library.

Marc's suggestion of enhancing the nat module for Sparc to detect
if the machine can run Sparcv9 is interesting, but we would still
have the same issue if we were cross debugging, no?
