aarch64-elf fails the ld-aarch64/bfd-far-3.d test, due to the stubs being emitted in a different order to that of aarch64-linux. They are emitted in a different order due to stub names for local symbols having the section id in the stub name. aarch64-linux-ld generates one more section than aarch64-elf-ld. That section is .gnu.hash. So the stub names differ and are hashed to different slots in stub_hash_table. Fix this by running the test with --hash-style=sysv, and adjust expected output. I've also changed the branch over stubs emitted at the start of a group of stubs to not care about the symbol, for all groups not just the one that needed changing. * ld-aarch64/bti-far-3.d: Add --hash-style=sysv. Adjust expected output.
