Build system updates (call for testers!)



Thanks for working on this.  A couple comments:

Currently, with gcl, sys-proclaim.lisp is made in one format
by "make sys-proclaim.lisp" and then overwritten in another 
format by "make".  I think you can just remove the line
	$(EXECUTEGCL) '(progn $(LOADDEFSYSTEM) (compiler::emit-fn t) $(DEFSYSTEMCOMPILE) $(LOADMAKEPROCLAIM) (compiler::make-all-proclaims "*/*.fn" "*/*/*/*.fn"))' && \
from the $(BINARY_DIR)/maxima target.

It would be nice if all automatically generated files disappeared
with "make clean".
