12d0ee4aca Avoid creating COPY relocs if possible.
* elf32-i386.c (elf_i386_check_relocs): Tweak condition under
	which .got created.  Mark symbols used by R_386_32 and R_386_PC32
	relocs as ELF_LINK_NON_GOT_REF to create COPY relocs only when the
	reloc is in a read-only section.  Instead, allocate space for a
	dynamic reloc to reference the library symbol directly.  Keep
	track of space we allocate using pcrel_relocs_copied.
	(discard_copies): Delete, and move code to ..
	(allocate_plt_and_got): ..here.  Rename to
	allocate_plt_and_got_and_discard_relocs.  Remove unneeded dynamic
	relocs for non-shared link.
	(elf_i386_size_dynamic_sections): Update calls to above functions.
	(elf_i386_relocate_section): Write out the dynamic relocs.  Add
	more ugly logic to avoid "unresolvable relocation" error.  Use
	htab shortcut in place of elf_hash_table macro.
	(elf_i386_finish_dynamic_sections): Allow that dynamic .got may
	not always be created now.

6725bdbfa9 * elf32-i386.c (elf_i386_discard_copies): Rename to

	(elf32_hppa_adjust_dynamic_symbol): ..and don't allocate .plt and

	(allocate_plt_and_got): ..instead do it all here.  New function.
	(elf_i386_size_dynamic_sections): Allocate local .got space and
	call allocate_plt_and_got.  No need to zap .relgot if not dynamic.
	(bfd_elf32_bfd_final_link): Delete.  (ie. use regular final link
	rather than gc variety).
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define.
	(elf_i386_relocate_section): Use it here and correct handling of
	R_386_GOT32.  Provide section and offset for "unresolvable
	relocation" error message.
	(elf_i386_finish_dynamic_symbol): Correct handling of R_386_GOT32.

	* elf32-i386.c (struct elf_i386_link_hash_table): Add sgot,
