fd161d860f Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library.  This patch defines them conditionally with PROVIDE, since a
shared library might need the local value.  An example is glibc ld.so
local access to "_begin", "_etext" and "_end".  (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)

We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable.  An
example is freebsd libc dynamic access to "_end".

d3a49aa80b readelf ngettext fixes
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.

Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages.  For now I'm punting on this
one.

Changes to readelf output require lots of testsuite adjustment..

3988aed54a PR22374, PowerPC unnecessary PLT entries
We don't need a PLT entry when function pointer initialization in a
read/write section is the only reference to a given function symbol.
This patch prevents the unnecessary PLT entry, and ensures no dynamic
relocs are emitted when UNDEFWEAK_NO_DYNAMIC_RELOC says so.

bfd/
	PR 22374
	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Don't create a plt
	entry when just a dynamic reloc can serve.  Ensure no dynamic
	relocations when UNDEFWEAK_NO_DYNAMIC_RELOC by setting non_got_ref.
	Expand and move the non_got_ref comment.
	* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise.
ld/
	* testsuite/ld-powerpc/ambiguousv2.d: Remove FIXME.

bab55c0522 Support different ld --hash-style in the ld testsuite
When ld is running with something other than --hash-style=sysv by
default, numerous tests need tweaking.  Most of the changes just add
--hash-style=sysv.  I didn't want to make --hash-style=sysv global as
that means --hash-style=gnu isn't well tested.

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.

d1eca1e41d Taking an undefined function's address in an executable
doesn't always mean you need to define a function symbol on plt code.
If all references are in read-write sections, then using dynamic relocs
is OK.

	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Clear
	pointer_equality_needed when !readonly_dynrelocs.
	* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise.
ld/testsuite/
	* ld-powerpc/ambiguousv1.d: Match symbol table too.

f6c7c3e8b7 Referencing a function's address on PowerPC64 ELFv2
ELFv2 needs to create plt entries in a non-PIC executable for an
address reference to a function defined in a shared object.  It's
possible that an object file has no features that distinguish it as
ELFv1 or ELFv2, eg. an object only containing data.  Such files need
to be handled like those that are known to be ELFv2.
However, this unnecessarily creates plt entries for the analogous
ELFv1 case, so arrange to set output abi version earlier, and use the
output abi version to further distinguish ambiguous input files.

bfd/
	* elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly
	needed plt entries when taking the address of functions for
	abiversion == 0 (ie. unknown) as well as abiversion == 2.
	Move opd setup and abiversion checks to..
	(ppc64_elf_before_check_relocs): ..here.  Renamed from
	ppc64_elf_process_dot_syms.  Set output abiversion from input and
	input abiversion from output, if either is not set.
	(ppc64_elf_merge_private_bfd_data): Don't merge flags here.
	(elf_backend_check_directives): Update.
