I suggest doing it roughly this way, assuming it will cure the problem.
But it can be done more cleanly.

Turn uses of "touch" into $(TOUCH), which is normally "touch" but
can be something else on systems with this bug.

Well, you could do it that way, but it is a much more major change.
And there may be other uses of touch that could still mess us up.
