[SPARC]: Handle UNWIND_INFO properly.
For sparc32 we need R_SPARC_UA32 relocation support, for
sparc64 we need the handle R_SPARC_DISP32 relocations.
Based upon reports and initial patch by Martin Habets.

If you say Y here the resulting kernel image will be slightly larger
but not slower, and it will give very useful debugging information.
