You can print the values of variables. I use something like:
$(warning here is what is in LOCAL_FILES $(LOCAL_FILES))

What you'll see when you issue make is: foo.c bar.c buzz.c 
here is what is in LOCAL_FILES

 Did you know that you can use remake -x to get a trace of
 what make is
 trying to build? You can also do a dry run to see what all
 make would do
 with make -n.
