compiler_wrapper: add a script to restore us to a working wrapper
Sometimes, I'm guilty of using ./install_compiler_wrapper.sh on broken
sources. Restoring the world to a working state requires
knowing/remembering a command. Seems better to provide that knowledge in
executable form.
BUG=None
TEST=Ran the script
