Alan Modra a27e685fa0 Align .TOC. for PowerPC64 
This change, with prerequisite 0e5fabeb, provides a toc base aligned
to 256 bytes rather than 8 bytes.  This is necessary for a minor gcc
optimisation, allowing use of d-form instructions to correctly access
toc-relative items larger than 8 bytes.

Alan Modra dbd1e97e32 PowerPC64 changes for xlc 
The changes to reorder sections for better relro protection on powerpc64,
3e2b0f31, 23283c1b, and 5ad18f16, run into a problem with xlc.
xlc -qdatalocal puts global variables into .toc, which means that .toc
must be writable.  The simplest way to accomplish this is to edit the
linker script to remove .toc sections from .got on detecting xlc object
files.

bfd/
	* elf64-ppc.h (struct ppc64_elf_params): Add "object_in_toc".
	* elf64-ppc.c (ppc64_elf_add_symbol_hook): Assume that global symbols
	in .toc indicate xlc compiled code that might require a rw .toc.

	* emultempl/ppc64elf.em (params): Init new field.
	(ppc_after_open): New function.

	* ldlang.c (lang_final): Whitespace fix.

	* ld-powerpc/tocnovar.d, * ld-powerpc/tocnovar.s: New test.

Alan Modra 5ad18f16ab Reorder more powerpc64 sections again for -z relro 
.toc1 is the second level TOC section used by gcc's -mminimal-toc.  It
too should be read-only after relocation.  Also, the last patch
description mentioned .sbss moving but didn't actually do that, so fix
that problem.  .tocbss (whatever that is) was before .sbss previously,
so move that one too.

	* emulparams/elf64ppc.sh (OTHER_SDATA_SECTIONS): Use in place of..
	(OTHER_BSS_SYMBOLS): ..this.
	(OTHER_PLT_RELOC_SECTIONS): Don't define.

	(OTHER_RELRO_SECTIONS_2): ..here.

Alan Modra 23283c1be0 Reorder more powerpc64 sections for -z relro 
This moves .got too, which requires .sdata and .sbss to move with it,
because these sections share addressing via the toc pointer and with
small-model code must be within a 16-bit signed offset.  .plt, .iplt
and .branch_lt must also be moved since they are addressed via a
32-bit offset from the toc pointer, and we might have a very large
.data section.

This change means we may have some bss style sections before the data
segment, necessitating another PT_LOAD header.  Also, since _edata is
defined at the end of the data segment it's possible with an empty
.data to have _edata at the end of .plt which looks a little unusual
since .plt is a bss style section.  That should only happen rarely in
real world binaries, but does occur in the ld testsuite.
