Bad zero comparison for sas_ss_flags on powerpc
All architectures work the same way, and all check for sas_ss_flags ==
0. The powerpc lines are wrong, and do the check the other way round
(it's a qemu internal check, which is done wrong only for this
architecture, it's more a typo than a bug). It's NOT ppc specific,
it's POSIX standard (sigaltstack) and qemu internal.
I have a test source that I will send in a follow-up (it's longer than
I would have wished, I'm sure that a better test case can be written
if needed)
