Alan Modra 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.

Alan Modra 45965137be Support R_PPC64_ADDR64_LOCAL
This adds support for "func@localentry", an expression that returns the
ELFv2 local entry point address of function "func".  I've excluded
dynamic relocation support because that obviously would require glibc
changes.

Alan Modra 2edab91c10 Make assignments to dot keep an empty output section.
An assignment to dot in an output section that allocates space of
course keeps the output section.  Here, I'm changing the behaviour for
assignments that don't allocate space.  The idea is not so much to
allow people to force output of an empty section with ". = .", but
to fix cases where an otherwise empty section has padding added by an
alignment expression that changes with relaxation or .eh_frame
editing.  Such a section might have zero size before relaxation and so
be stripped incorrectly.
