since all you're doing is adjusting all the paths to get at the top of the 
tree, i wonder if you shouldnt just introduce a new variable for the top and 
then base everything off that.

OBJTREETOP = $(OBJTREE)$(SUBTREE)

and then in the spl subdir, you set SUBTREE to "/../..".  this would avoid 
sprinkling of a specific CONFIG option throughout the build system.
