Skip extra relocations in .rel.plt/.rela.plt
Extra relocations may be added to the .rel.plt/.rela.plt section, which are unrelated to PLT. We should skip them when retrieving PLT entry symbol values. PR binutils/18437 * elf32-i386.c (elf_i386_get_plt_sym_val): Skip extra relocations in .rel.plt/.rela.plt. * elf64-x86-64.c (elf_x86_64_get_plt_sym_val): Likewise.
