+[AArch64] Fix erroneous use of spu architecture bfd
+
+While investigating some SVE code, i noticed the use of two spu bfd variables.
+
+This looks like an oversight, as the "id" field is available for non-spu
+architectures as well, even though its primary use was the Cell BE
+architecture.

+	* aarch64-linux-nat.c
+	(aarch64_linux_nat_target::thread_architecture): Use bfd_arch_aarch64
