Randy,
I like that this approach doesn't muck with /usr/ports/Mk/. I doubt I
would have discovered __MAKE_CONF on my own, but now that I know to look
for it, I see that it's covered early in make(1):
First of all, the initial list of specifications will be read from
the system makefile, sys.mk, unless inhibited with the -r option.
The standard sys.mk as shipped with FreeBSD also handles
make.conf(5), the default path to which can be altered via the
make variable __MAKE_CONF.
