[PATCH] ia64: fix sigaction decoding

[Mike Frysinger]

Looks like ia64 doesn't have sa_restorer either, yet still defines
SA_RESTORER.  Deploy the same trick that HPPA is using to make the
test pass.

* signal.c (SA_RESTORER): Undefine when IA64 is defined.
(struct new_sigaction): Disable sa_restorer on ia64.
