[GOLD] PowerPC tweak relnum tests
There is a call of relocate() to perform a single relocation. In that
case the "relnum" parameter is -1U and of course it isn't appropriate
to consider any of the PowerPC code sequence optimisations triggered
by a following relocation.
* powerpc.cc (Target_powerpc::Relocate::relocate): Don't look
at next/previous reloc when relnum is -1.
