packaging mistake? aarch64 linux tarball seems to contain x86_64 binary, not aarch64

I just downloaded the aarch64 Linux tarball, and it appears that the binary packaged inside it is actually an x86_64 binary. (I think this issue is actually the problem the person is noticing in issue #24 - I think the provided executable cannot possibly run on a machine with an aarch64 CPU, barring some inline emulation trickery.)
