This example was just to explain the kind of situation in which I am.
The details of my situation are a bit different, but yes: I do want to
take "whatever is there" because my makefile is used to maintain/build
arbitrary Emacs Lisp packages from a clone of their Git repository.

In any case, the "second expansion" trick mentioned by Paul (which I had
forgotten) should be good enough for my immediate needs.  BTW, maybe the
section of the manual I quoted should mention this "second expansion".

Thanks,
