commit 3ba720c788c2845c93a6dfe592f36163cbfa63fd

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