Here's where I'm at now:
REFRESH+ldb+celltools+pub := dogs
all :
@list=REFRESH+ldb+celltools+pub ;\
echo "list = '$$list'" ;\
echo "contents = '$($$list)'" ; \
def=$(origin $$list); \
echo "def = $$def" ; \
if ! [ "$$def" = "undefined" ] ; then \
echo "if defined"; \
else \
echo "else undefined" ; \
fi
