You don't, in make(1)?  (This is pretty long standing `tradition'.)

: I suspect the solution is to provide a modifier that defines the
: separator to use, or a modifier that allows one to a regexp
: substitution on the expanded buffer.

To keep from doing something really drastic (such as warping C/// or S/// to
work on the whole string 8-), I'd suggest a "join" operator -- such that
doing something like ${VAR:J,} would replace the separator with a ",".

(A "split" operator is not necessary; this can be done with S///.)
