#!/bin/bash
# this script creates a wrapper shell script for an executable.  The idea is the actual executable cannot be
# executed natively (it was cross compiled), but we want to run tests natively.  Running this script
# as part of the compilation process will move the non-native executable to a new location, and replace it
# with a script that will run it under qemu.
