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.

2013-12-16  Andreas Schwab  <schwab@suse.de>
* elf64-ppc.c (ppc64_elf_relocate_section): Add newline to error
message.

libiberty: fix --enable-install-libiberty flag [PR 56780]

Commit 199570 fixed the --disable-install-libiberty behavior, but it also
added a bug where the enable path never works because the initial clear
of target_header_dir wasn't deleted.  So we end up initializing properly
at the top only to reset it at the end all the time.

ld/testsuite/ld-aarch64: Fixup IFUNC tests to work on all targets

More PowerPC64 ELFv2 --just-symbols fixes

I don't know what I was thinking here to omit the save of r2.
Possibly I was looking at -msave-toc-indirect code at the time, where
r2 is saved in the function prologue.

* elf64-ppc.c (ppc_build_one_stub <ppc_stub_plt_branch_r2off>):
Don't omit saving of r2 for ELFv2.  Don't addi 2,2,0.

PowerPC64 linking of --just-symbols objects (klibc)

With -mcmodel=medium we can't assume that a -R object doesn't use
toc-relative addressing if there's no toc.  Lots of things are
accessed via r2, not just the toc/got section.  Also, testing for
.opd is plain wrong for ELFv2.

* elf64-ppc.c (ppc64_elf_link_just_syms): Remove .got check.
Handle ELFv2.
