It appears to work (but doesn't have much effect without an rs6000

One question (and to follow up my earlier post) is there a better way of
doing this:
+ if (frame_pc_unwind (next_frame) > 0x7f000000)
+ /* Assume anything that is vaguely on the stack is a signal
+ trampoline. */
+ return &ppcnbsd_sigtramp_unwind;
ok?, eventually for 6.1?
For other targets, we grub in the code for the sigtramp instruction
sequence. I'm betting it's fixed for NetBSD too? ppc_linux_in_sigtramp
does this.
