description:
Restore COMPAT_IRIX signal delivery to an usable state. We provide a
fake sigcode so that trampoline vers checks in sigaction1() will not
return EINVAL. Another fix would be to duplicate code from svr4_sys_sigaction()
to irix_sys_sigaction() and call sigaction1() with vers != 0. We do not
do that because it would duplicate some code.
