* 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.
