This is not a bug.  Double colon implicit rules have a different meaning than double-colon explicit rules.  See the section "Match-Anything Pattern Rules" in the GNU make manual.

Consider the makefile

pat=$(filter-out %/,$(subst /,/ ,$@))

@echo "$(pat) 1"

@echo "$(pat) 2"

@echo "test 1"

@echo "test 2"

I'd hoped that "make target/test" would run the two double-colon pattern rules, like "make target" does. However, this appears not to be the case. If this is a bug or not is definitely a matter of opinion, but having this feature would certainly be useful to me..
