I think you should want to declare such a target as .PHONY, agreed Paul?

That target has no recipe, so there's nothing to build the target. I
guess a more detailed way to say it would be that any rule that builds
an actual target file on the disk must always build the one that the
rule says it will build.

If you have a target that doesn't actually create a file (like "all"
for example, or this shortcut target) then the rule that the created
file must match the target doesn't apply.
