[PATCH 0/3][RFC] powerpc: relative exception tables, and build-time sort

[Nicholas Piggin]

This implements relative exception tables for powerpc, and converts it
to use build-time sorting. I've tested 64s only so far, but 32-bit seems
to build. Will obviously require some more testing and reviews.

Thanks,
Nick
