Not without recursion.  Sorry.

Well, you can break the makefile into two parts so that only the
necessary parts are included in when you invoke the right make.

If you don't want to physically break it up you can logically break it
up by using ifeq, etc. to only parse the proper part of the file.  For
example you can check the value of $(MAKECMDGOALS) to decide which
section of the makefile should be visible to the current invocation of
make.


That's about the only suggestion I have.
