[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.
gdb/ChangeLog:
2020-01-05 Luis Machado <luis.machado@linaro.org>
* aarch64-linux-nat.c
(aarch64_linux_nat_target::thread_architecture): Use bfd_arch_aarch64
and bfd_mach_aarch64.
