Currently POSIX does not require unset macros to expand to an empty

It seems like this is an opportunity to standardize behavior that is
common across multiple (all?) make implementations.
The proposed change *reduces* the allowed behaviours from many to
just two.
If all make implementations have the same behavior, why not standardize
that?
Is there evidence that the "typo in the makefile" problem is widespread
enough to devise and require a hypothetical fix in make?
