This fixes a "bug" in that nops emitted as part of code optimization were being relocated. As it happens the relocation value was always zero so the nop wasn't changed. Whew! I've also moved the use of "howto" later since I was caught out in some recent code changes with the howto not matching r_type. * elf64-ppc.c (ppc64_elf_relocate_section): Don't relocate nops emitted for toc sequence optimization. Set and use "howto" later.
