	* elf32-sh.c (sh_elf_copy_indirect_symbol): New.
	(create_got_section, allocate_dynrelocs, readonly_dynrelocs):
	Likewise.
	(struct elf_sh_pcrel_relocs_copied): Removed.
	(struct elf_sh_dyn_relocs): New.
	(struct elf_sh_link_hash_entry): Replace pcrel_relocs_copied
	field with dyn_relocs.
	(struct elf_sh_link_hash_table): Add short-cuts to get dynamic
	sections and sym_sec.
	(sh_elf_link_hash_newfunc): Clear dyn_relocs.
	(sh_elf_link_hash_table_create): Clear shorts-cuts and sym_sec.
	(sh_elf_create_dynamic_sections): Use create_got_section instead
	of _bfd_elf_create_got_section.
	(sh_elf_check_relocs): Likewise.
	(sh_elf_create_dynamic_sections): Use short-cuts to the dynamic
	sections.
	(sh_elf_adjust_dynamic_symbol, sh_elf_size_dynamic_sections,
	sh_elf_relocate_section, sh_elf_check_relocs,
	sh_elf_finish_dynamic_symbol, sh_elf_finish_dynamic_sections):
	Likewise.
	(sh_elf_adjust_dynamic_symbol): Handle nocopyreloc. Keep the
	dynamic relocations and avoiding the copy relocation when we
	didn't find any dynamic relocations in the section which has
	contents or is read-only.
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): New.
	(sh_elf_size_dynamic_sections): Don't reset the size of
	.rela.got section even if dynamic_sections_created flag is off.
	Don't use sh_elf_discard_copies. Scan all input bfd and use
	allocate_dynrelocs. Call readonly_dynrelocs to determine
	whether we need DT_TEXTREL.
	(sh_elf_adjust_dynamic_symbol): Use plt.refcount to determine
	whether the symbol was never referred to.
	(sh_elf_relocate_section): Use WILL_CALL_FINISH_DYNAMIC_SYMBOL.
	(sh_elf_gc_sweep_hook): Fill with the real sweep function.
	(sh_elf_check_relocs): Call create_got_section if the short-cut
	to .got is null. Increment reference counters only instead of
	allocating space on dynamic sections here. Don't conditionalize
	uninitialized got.offset value when marking the symbol as a
	global offset table entry. Keep relocations for symbols satisfied
	by a dynamic library to avoid copy relocations for the symbol.
	Set dynobj field of an elf hash table if needed.
	(sh_elf_finish_dynamic_sections): Handle null section pointer
	correctly.
	(elf_backend_copy_indirect_symbol): Defined.
	(elf_backend_can_refcount): Defined.
