* elf32-hppa.c (elf32_hppa_gc_sweep_hook): Simplify dynamic reloc
removal. Localize vars. Remove unnecessary dynobj test.
* elf32-i386 (WILL_CALL_FINISH_DYNAMIC_SYMBOL): Pass SHARED instead
of INFO.
(allocate_dynrelocs): Adjust WILL_CALL_FINISH_DYNAMIC_SYMBOL uses,
and optimize.
(elf_i386_relocate_section): Likewise.
(elf_i386_gc_sweep_hook): Simplify dyn reloc removal. Localize vars.
* elf32-s390.c (elf_s390_gc_sweep_hook): Likewise.
* elf32-sh.c (sh_elf_gc_sweep_hook): Likewise.
* elf64-s390.c (elf_s390_gc_sweep_hook): Likewise.
* elf64-x86-64.c (elf64_x86_64_gc_sweep_hook): Likewise.
* elf32-sparc.c (elf32_sparc_gc_sweep_hook): Likewise. Remove
local_dynrel for section too. Don't touch HIPLT22, LOPLT10, PCPLT32
or PCPLT10 relocs. Don't subtract twice on PLT32 relocs.
Formatting.
