I was mistaken in my initial impression; this actually isn't a bug. In
fact, it's documented behavior. The GNU make manual says:
Since it knows that phony targets do not name actual files that
could be remade from other files, `make' skips the implicit rule search
for phony targets (*note Implicit Rules::.). This is why declaring a
target phony is good for performance, even if you are not worried about
the actual file existing.
So, you cannot mark a target as .PHONY if you want to use it in an
implicit rule search; make won't do implicit rule searches on .PHONY
targets.
You can use the FORCE alternative to .PHONY, or you can use static
pattern rules instead of implicit rules.
HTH...
