Differences between OpenBSD and FreeBSD -V option in make

While working on a portupgrade-like utility for OpenBSD, I've noticed that FreeBSD's make and OpenBSD's make treat the -V option differently.

FreeBSD-make recursively evaluates the variable(s) provided, while OpenBSD-make does not. This variable expansion is a feature I need for the portupgrade utility.

Example Makefile...

DISTNAME=       Atlas-C++-${VERSION}
PKGNAME=        ${DISTNAME:S/C++-//:L}

# make -V PKGNAME

FreeBSD-make returns 'atlas-0.4.3.1'
OpenBSD-make returns '${DISTNAME:S/C++//:L}'

I've created a patch for make which mimics the FreeBSD expansion with the same option (-X) to disable expansion.

Is this feature currently missing because it *should* be missing?

The patch may be found at either of the two following links. As I'm new to this, comments would be greatly appreciated.
