Which would only be correct if building the same version of FreeBSD as
is running on the host.
Many folk work on multiple branches on the same machine.

Thus for anyone working on src/ there is no guarantee that /usr/share/mk
is even remotely correct.

So you either buy into the idea of using a wrapper script and canned
.env file for each tree (that's what I do;
http://www.crufty.net/sjg/docs/sb-tools.htm) to ensure correct 
settings per tree (whether FreeBSD, NetBSD, ...), or you compromise and
have 'make' itself try to find the "correct" share/mk for whereever it is.
This is why the default MAKESYSPATH starts with .../share/mk

Yes, but requires you to keep /usr/share/mk in sync with whatever you a
building, tricky if you build head, stable/10 and stable/11 on the
same box.
