* elf32-arm.h (elf32_arm_final_link_relocate): Don't copy STN_UNDEF
relocs into shared libs.

(struct bfd_elf_section_data): Change local_dynrel type to PTR.
* elflink.h (elf_link_input_bfd): Don't test for removed linkonce
relocs when relocatable. Don't zero entire reloc, just zero the
addend and sym.
* elf32-i386.c (struct elf_i386_link_hash_table): Add sym_sec.
(elf_i386_link_hash_table_create): Init it.
(elf_i386_check_relocs): Track dynamic relocs needed for local
syms on a per-section basis as we do for globals.
(elf_i386_gc_sweep_hook): Update for local_dynrel change.
Remove dead code.
(allocate_dynrelocs): Warning fix.
(elf_i386_size_dynamic_sections): Don't allocate relocs when
section has been discarded.
