[GOLD] Correct powerpc64 ifunc plt entry test

[Alan Modra]

Found when attempting to build an ELFv2 Linux kernel.  We don't
generally need a plt entry for ELFv2 got relocs, only on ifunc, just
like ppc32.

	* powerpc.cc (Target_powerpc::Scan::local <got relocs>): Correct
	condition for need of ifunc plt entry.
	(Target_powerpc::Scan::global <got relocs>): Likewise.
