* elf32-ppc.c (ppc_elf_relocate_section): Don't emit R_PPC_REL*
 	relocs in shared libraries which refer to local symbols.  Cope
 	with addend when processing a GOT relocation.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Only create symbols
	for sections that the linker didn't create.
	(ppc_elf_finish_dynamic_sections): Only try to write out a section
 	symbol if it was created in ppc_elf_size_dynamic_sections.
	(ppc_elf_relocate_section): Complain if we have to generate a reloc
	relative to a section for which we didn't output a symbol.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Clean up.  PLT
 	relocs are 'rela' relocs, like everything else.  .rela.plt is not
 	a read-only section, so we don't have to special-case it.

	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Entries in the
	.rela.bss section are (of course) 'rela' relocs not 'rel' relocs.

	* elf32-ppc.c (ppc_elf_check_relocs): Initialise srelgot.
	(ppc_elf_relocate_section): @got offsets are 4 from start of the
	actual .got section.
	* elflink.c (_bfd_elf_create_got_section): The three reserved
	words start from the symbol '_GLOBAL_OFFSET_TABLE_'.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): '.rela' is 5
	characters, not 4.

	* elf32-ppc.c (ppc_elf_check_relocs): Use
	_bfd_elf_create_got_section to create the GOT rather than
	ppc_elf_create_linker_section. Create the '.rela.got' section
	ourselves.
	(ppc_elf_finish_dynamic_symbol): Set up GOT relocations when a
	symbol has a GOT entry.
	(ppc_elf_relocate_section): Record when a symbol is used through
	the GOT, and allocate space in the GOT for each such symbol.
	(ppc_elf_adjust_dynamic_symbol): Delete unused .got.plt stuff.
	(ppc_elf_create_linker_section): Delete unused LINKER_SECTION_GOT
	stuff.

	* elf32-ppc.c (ppc_elf_howto_raw): GOT16_HA relocs should be
	treated in a similar way to ADDR16_HA relocs.
	(ppc_elf_relocate_section): PLTREL24 relocs do not get copied into
	shared objects; the linker must deal with them.
	(ppc_elf_create_linker_section): Stop setting
	_GLOBAL_OFFSET_TABLE_ to the wrong value; delete unused
	LINKER_SECTION_PLT stuff.
	(ppc_elf_check_relocs): Delete unused LINKER_SECTION_PLT stuff.
	(ppc_elf_finish_dynamic_sections): Use BFD calls to get GOT
	section, not ELF-specific calls.
	(elf_backend_plt_not_loaded): Set to 1.
	(elf_backend_got_symbol_offset): Set to 4.
	* elf-bfd.h (elf_backend_data): Add 'plt_not_loaded' member
	for when ld.so fills in the PLT; and 'got_symbol_offset' member.
	* elflink.c (_bfd_elf_create_dynamic_sections): Apply
	plt_not_loaded member.
	(_bfd_elf_create_got_section): Apply got_symbol_offset.
	* elfxx-target.h (elf_backend_plt_not_loaded): Set default to
	'loaded'.
	(elf_backend_G_O_T_offset): Set default to 0.
	(elfNN_bed): Set added fields.

	* elf32-ppc.c (ppc_elf_size_dynamic_sections): Was setting
	DT_RELENT in shared objects; should be DT_RELAENT.

	* elf32-ppc.c (ppc_elf_relocate_section): Propagate
	R_PPC_ADDR16_HA relocs to shared objects. Cope with case where
	such a reloc (in a non-shared object) refers to a symbol that's
	not defined.

ede4eed483 Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions.  Added a
pointer to that structure to the target back end data.  More work can be done
here.

Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf.  Updated most call sites, sometimes defined some macros.

Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior.  More work can probably be
done here too.

Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c.  Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h.  Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.

Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.
