[Bug ld/11088] Internal Error in ppc64_elf_gc_sweep_hook

[Alan Modra]

Applied.  I'll apply similar fixes later to elf32-ppc.c.  I'm on
holiday and supposed to be house painting, not sitting in front of a
computer.  :-)

	PR ld/11088
	* elf64-ppc.c (ppc64_elf_gc_sweep_hook): Don't abort if symbol
	hiding has nulled out plt.plist.
