So the sigpending() system call returns the pending signals as an int value via register, but then the libc stub is supposed to take care of storing this as appropriate.
If you look at libc/arch/amd64/sys/sigreturn.S, you'll notice there's some followup assembly code for this. It looks like the analogous code is missing from libc/arch/powerpc/sys/sigreturn.S.
