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

Browse Source 
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.

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