The $$@ syntax is not standard (although various SystemV based versions
of make support it).
GNU make supports that syntax starting with version 3.80, but even that
version doesn't support substitutions on it like this.
ln> $(DERIVED_DIRS:=/.touch): $$(@:/.touch=)
ln> @echo "TOUCH $@ "
See the GNU make manual for GNU make 3.79; there's a section there on
"Missing Features and Incompatibilities" and the solutionthey give for
the $$@ feature is what you Want: static pattern rules:
$(DERIVED_DIRS:=/.touch) : %/.touch : %
@echo "TOUCH $@ "
