Where are all these defined? Can't find them in make(1) nor "Pmake - A
Tutorial" nor /usr/share/mk/.

Is there a list of (un)supported configurations? What I gather is that
one of the following must be true:

1.- build and install machines are the same release level (or I can somehow
"cross-build" 4.8.p2 from 4-STABLE?)
2.- build and install machines are the same arch (or __MAKE_CONF can
overcome this?)
