compilation under emulation produces broken executables

[mschwaig]

Like #45 I am interested in producing binaries for a different architecture.

I'm using the nix bundle command. I hope this is the right place to file issues for nix bundle and I can see that the README.md file here points out some limitations:

This is a standalone file that is completely portable! As long as you are running the same architecture Linux kernel and have a shell interpreter available it will run.

This makes me think that what I'm trying to do is not supposed to work yet.

On my x86_64 Linux machine running

$ nix bundle nixpkgs#legacyPackages.aarch64-linux.hello

succeeds, but produces a binary which fails to launch

$ ./hello
execvp(/nix/store/1ncnl3siyp20h6rwvpjb756mp7347nwb-hello-2.12.1/bin/hello): No such file or directory

It would of course be great if this was working, but I think it would already be an improvement if it wasn't failing silently.
