The whole point of 6abc8c2596 AIUI was to have this program not
installed (that's why for the test we need to get it from $TESTDIR where
it's built except when we're using MSVC). That commit should probably
have made sure the MSVC install process likewise didn't install it. So
ISTM that relying on it being installed is going in the wrong direction.
