* elf32-ppc.c (struct ppc_elf_dyn_relocs): Add pc_count field.

	* elf32-ppc.c (struct ppc_elf_dyn_relocs): Add pc_count field.
	(ppc_elf_copy_indirect_symbol): Copy pc_count field.
	(ELIMINATE_COPY_RELOCS): Define.
	(ppc_elf_adjust_dynamic_symbol): Convert copy relocs to dynamic.
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Pass SHARED instead of INFO.
	(MUST_BE_DYN_RELOC): Define.
	(allocate_dynrelocs): Adjust WILL_CALL_FINISH_DYNAMIC_SYMBOL uses,
	and optimize.  Trim dyn_relocs.
	(ppc_elf_check_relocs): Don't generate dyn_relocs when we know they'll
	not be used.  Do generate dyn_relocs for copy reloc avoidance.  Keep
	track of pc_rel dyn relocs.

	WILL_CALL_FINISH_DYNAMIC_SYMBOL use.  Trim dyn relocs as per
	allocate_dynrelocs.  Don't recalculate "sec".
