* Makefile (ABBREV): Rewrite to take advantage of DEP_

variables to remove the dependencies from the output.
(ABBREV2): No longer needed, removed.
(dbg/%.o, opt/%.o, %.o): Just use ABBREV instead of ABBREV2; it does
the right thing.  Dependency of objects on config.make removed.

* dep.mk: Regenerated. Now provides variable assignments
in addition to rules, and each object is made dependent
on config.make.

* depend.txr: Adjusted to generate dep.mk in new format.
