Hmm... There's something odd going on with {rt_,}sigaction on sparc -
we *do* have sa_restorer in struct sigaction and struct old_sigaction,
but it's not used for anything whatsoever. There's also a separately
passed restorer pointer for rt_sigaction() and *that* is used instead,
but not reported via *oact.
What's the reason for that weirdness? I understand why we do that on
alpha (we have no sa_restorer in struct sigaction we'd inherited from
OSF/1), but sparc always had perfectly normal sigaction->sa_restorer
field all along - even for old sigaction(2)...
