Force the AArch64 linker backend to refuse to link when it encounters unresoleable relocations.
* reloc.c (enum bfd_reloc_status): Start values at 2. * bfd-in2.h: Regenerate. * elfnn-aarch64.c (aarch64_relocate): Invert sense of function, so that a TRUE return indicates success. Compare the result of calling _bfd_aarch64_elf_put_addend against bfd_reloc_ok. (build_one_stub): Change sense of tests against aarch64_relocate return value. (elfNN_aarch64_tls_relax): Return bfd_reloc_notsupported, rather than FALSE, when an error is detected. (elfNN_aarch64_final_link_relocate): Likewise. * testsuite/ld-aarch64/pcrel_pic_defined.d: Expect errors not warnings. Expect errors about unsupported relocations. * testsuite/ld-aarch64/pcrel_pic_undefined.d: Likewise.
