Weird. My 'make' inherited them both. Here is small test example:

dima@tejblum|/usr/home/dima/misc/mktest>cat Makefile
world:
	make buildworld

buildworld:
.ifdef NOCLEAN
	@echo With NOCLEAN!
.endif
.ifndef NOCLEAN
	@echo Without NOCLEAN!
.endif
dima@tejblum|/usr/home/dima/misc/mktest>make world
make buildworld
Without NOCLEAN!
dima@tejblum|/usr/home/dima/misc/mktest>make -DNOCLEAN world
make buildworld
With NOCLEAN!
dima@tejblum|/usr/home/dima/misc/mktest>exit
