(sorry, I couldn't comment on this before the commit)
When you're installing from an older system(-RELEASE, for example)
using DESTDIR, `make upgrade' fails because it uses older <sys.mk> in
the installing system, rather than from the source tree or from
$DESTDIR/share/mk.  If I specify the share/mk in the source tree using
MAKEFLAGS, it seems to work fine.
