# HACK: Target is getting touched because timestamps of the generated
#       object file don't change unless there's an actual change in the
#       outputted object code. This results in this target running every
#       single time. I'm not sure whether that's the exact reason, but
#       I can't imagine why timestamps wouldn't change. When clang
#       generates same exact executable, timestamps do change.
