just to be clear, if such a reference to a non-existent CONFIG
variable can be removed from a Makefile, that normally implies that
what it was managing (the source file) can *also* be removed since
there will, of course, be nothing to force its compilation.

  in the above case, there just happens to be no file i2c.c in that
directory so it's not a problem, but if there had been, the patch to
take care of this would have involved deleting that source file.  as
long as we understand that.

  i may remove the removable stuff in more than one patch if they look
like logically separate operations.
