Rather than the MIPS, check the x86 family for how to add a custom
sigtramp handler (ex, i386_sigtramp_frame_sniffer). Hopefully the new
mechanism is less baffling - the current MIPS code is not a good reference.
But since he's got a MIPS target, the frame sniffers won't help him at
all, will they? They can't be used until the MIPS is converted.
