Eliminating R_PPC_REL32 relocations

[David Dunkle]

I haven't been looking at shared libraries but at object modules
subsequently linked into executable images. Perhaps its irrelevant.

I am surprised that jump tables are resulting in REL32 relocs in a shared
library.  The jump table entries should be relative addresses of
*local* labels, and so need no relocation in the final link output.
