Fixes powerpc64le ld segfaults when --emit-relocs is used.

ELFv2 needs fewer relocs to annotate plt call stubs.  I correctly
allocated a smaller buffer and wrote the proper relocs, but stupidly
bumped the reloc count as for ELFv1.

Also backport a couple of other minor fixes.

	* elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed
	to get_relocs for ELFv2.
	(STK_LINKER): Comment typo fix.

	* elf64-ppc.c (ppc64_elf_relocate_section): Add newline to error
	message.
