It would be great to have a simple example on how to use QEMU in a workflow in the README.

We provide two simple examples of invoking `qemu-{arch}-static` (or more
precisely, we let the kernel do the invocation.)

Closes: docker#95

There were two things that confused me in the beginning, so let me give the information here:

  • This action is named setup-qemu-action, but it only sets up user mode emulation. You can't use qemu-img or any qemu-system-* functionality.
  • No qemu-* binaries added to the path. Instead they are registered with the kernel (using binfmt_misc), and the kernel will invoke the correct qemu-* binary by looking at the first few bytes of an executable. Thus, qemu-aarch64-static hello will fail, but ./hello works fine.
