Unfortunately I can't, because I don't have access to any sparc debian
systems, and cros-running testsuite doesn't seem to be possible.
Probably somebody on the list may help? I'm reattaching the fix to make it
available on list. The fix is not cross-specific, show thing to test is
that it doesn't break anything for native sparc compilers.

Again, I can't help, I don't have hardware access.
