Verify Arm executables to run on x64 machines

To verify the qemu handlers are registered properly, run the following and make sure the first line of the output is “enabled”. Note that the handler registration doesn’t survive a reboot, but could be added to the system start-up scripts. REVERIFY AND REDO

$ cat /proc/sys/fs/binfmt_misc/qemu-aarch64

interpreter /usr/bin/qemu-aarch64
