Follow-up Comment #4:
My idea below was dumb.
What I ended up doing is that if we detect a recursive expansion in the
context of a shell function, we use the value of the variable from the
environment make was invoked with, or the empty string if the variable wasn't
present in the invoker's environment.
This gives us back the previous behavior. It's kind of bizarre but no worse
than any other choice, IMO.
