* elf/rtld.c: Include <string.h>. * elf/dynamic-link.h (ELF_DYNAMIC_DO_REL, ELF_DYNAMIC_DO_RELA, ELF_DYNAMIC_RELOCATE): No longer take RESOLVE argument. Conditionalize defns on [RESOLVE]. * elf/do-rel.h (elf_dynamic_do_rel): Likewise. * sysdeps/i386/dl-machine.h (elf_machine_rel): Likewise. Instead use RESOLVE macro with same args. (elf_machine_rel): Conditionalize defn on [RESOLVE]. * elf/dl-reloc.c (RESOLVE): New macro, define before including "dynamic-link.h". It replaces `resolve' local function. * elf/dl-runtime.c: Likewise. * elf/rtld.c: Likewise.
