PowerPC64 abort due to dynamic relocs on hidden undefweak

ppc64_elf_relocate_section lacked a check which meant that it emitted
dynamic relocs against a hidden undefweak symbol for which no dynamic
relocs had been allocated.

	PR 21224
	PR 20519
	* elf64-ppc.c (ppc64_elf_relocate_section): Add missing
	dyn_relocs check.
