You can generate the Makefile rules automatically:
LIST1 = a b c d
LIST2 = 1 2 3 4
Rules : Makefile
for x in $(LIST2); do \
echo "$(LIST1:%=%_$$x) : %_$$x : %"; \
echo ' echo $$* "'"$$x"'"'; \
done > Rules
include Rules
You might also want a target for creating everything:
ALL := $(shell for x in $(LIST1); do for y in $(LIST2); do \
echo $${x}_$${y}; done; done)
all : $(ALL)
And your original Makefile didn't specify how to create `a', `b', etc.,
so you may want to fill in some rules for them:
$(LIST1) : ...
