I got curious, so I checked the Single Unix Spec for make:
In an inference rule, $< evaluates to the filename whose
existence allowed the inference rule to be chosen for the
target. In the .DEFAULT rule, the $< macro evaluates to the
current target name. The $< macro is evaluated only for
inference rules. For example, in the .c.a inference rule, $<
represents the prerequisite .c file.
So I think this is a good patch.
