syscall-reset test on powerpc

Hi Jan,

Can we disable syscall-reset test case for powerpc, since it is broken there?

I think that is for powerpc not powerpc64, right? I have also only seen such failure on biarch run at the moment if I remember correctly. I am wondering something like if we see it is __powerpc__ but not __powerpc64__, and then sent out a message to state that the test does not support powerpc. What do you think?

Thanks,
CAI Qian
