[lug] How do you setup a recursive make?

[David Morris]

The reason your makefile below is failing is that 
"make -C $(CORE_DEPS)" is going to the directory
"../../../basic_services/dm", and making target "..../app".  What you
need to do is setup a loop to call "make -C" for each subdirectory
seperately, instead of all at once.
