Convert PLT reloc only if pointer equality isn't needed When pointer equality needed, we can't replace PLT relocations with GOT relocations for -z now. This patch checks if pointer equality is needed before converting PLT relocations to GOT relocations. bfd/ PR binutils/18458 * elf32-i386.c (elf_i386_check_relocs): Create .plt.got section for now binding only if pointer equality isn't needed.
