oh, i know *that* works but, as you can see, that make command has
enough info (the "M=" variable) to kick the Makefile into
module-building mode, so things work properly.

the original problem, of course, is still there.  but i think i've
flogged this sufficiently.  i'll leave someone else to do the fixing.
