The problem is that in gdb/configure.tgt there is no link to the compiled simulator. The patch below adds this link for aarch64-elf targets. I believe the reason for this is that the aarch64 simulator is considered deprecated in favour of using QEMU. Or it could just be an oversight that this link is missing. Either way, this should get it working for you.
