Sorry, but you have to double-escape the "$" in the rule.
When you invoke "call", it will expand the value (it has to, to replace
the arguments like $(1)!) so that undoes one level of $ escaping. Thus
when your rule is defined it will be:
test:
awk '{if (NF > 1) {print $1 " " $2} }' < Makefile
and when make expands it, the $1 and $2 will drop out. You can use
"make -p" to see this.
You need:
define TEST_RULE
.PHONY: $(1)
$(1):
awk '{if (NF > 1) {print $$$$1 " " $$$$2} }' < Makefile
endef
