I'd call this an "obvious fix", except for the fact that elf32_ppc.c
specifically mentions R_PPC_NONE in the group of relocations "that
always need to be propagated if this is a shared object".  Go ahead
and apply it anyway;  The only real use I can think of for a _NONE
reloc is in tying sections together during --gc-sections, and I don't
think ppc binutils does anything like that.
