Yes.

Then you have two choices.  The first is to use make's auto-re-exec
feature to dynamically construct a makefile containing the proper rules,
which you can include using make's "include" feature.  This is the
traditional way to support non-static data in makefiles which can't be
handled through make's normal implicit rule support.

The second is to wait for a bit:

:)

There's a pretest of this release available now, if you want to try it
(I'd actually like someone to test this capability in a "real life"
situation before the official release).
