For avoidance of doubt, I'm not suggesting to modify PATH from within
the Makefile. I'd do that before invoking 'make'.

And thus, running tests individually should work just as fine, and pick
up executables according to your settings.

Setting up the environment with a convenience script sounds fine, but I
still don't understand why this would be called by the test harness,
rather than manually before the test harness is invoked. Keeping the two
separate sounds much simpler and less error-prone to me.
