I have even built FreeBSD i386 from FreeBSD amd64, and vice versa.

Even when the user tracks only one branch, such as HEAD, one or more 
/usr/share/mk files may have been updated since the last build, and therefore 
not in sync with the build host's /usr/share/mk .

For building the system, MAKESYSPATH should be $SRCDIR/share/mk , to be in sync.

I tried "make -V MAKESYSPATH" from several SRCDIRs, and that's what happened.

Like this:

$ make -C /usr/src -V MAKESYSPATH
$ make -C /freebsd-base-graphics -V MAKESYSPATH

Something like that might be appropriate for ports but not for building the 

So maybe I have to set MAKESYSPATH every time I am in ports, don't know if this 
would work from /etc/make.conf (need to experiment).

I wonder what would happen if there is no FreeBSD installation at all on 
partition where ports tree is located.

I don't think you have to do that, since I find that MAKESYSPATH becomes 
$SRCDIR/share/mk .
