Um, Curt, I direct your attention to this part of the `build' target:

	.if exists(domestic) && !defined(EXPORTABLE_SYSTEM)
		(cd ${.CURDIR}/domestic && ${MAKE} ${_J} _SLAVE_BUILD= build)
	.endif

There is nothing broken here.  Do not `attempt' to `fix' it.

grep _BUILD src/Makefile
grep _DISTRIB src/Makefile src/etc/Makefile

There's more complicated things going on here than these two (internal)
variables.  Don't mess with this unless you understand it.
