NetBSD needs a *very* minimal set of POSIX tools to build, e.g. you can
get away with an sh(1) utility and a pretty basic make(1) tool.  They
have really done a magnificent job at constructing a build system that
can bootstrap itself from a tiny set of build tools.

FreeBSD also has _some_ of the necessary build glue to do similar sort
of stuff, but AFAIK we only support cross-building from one FreeBSD
architecture to another FreeBSD architecture.  So you need to have at
least *some* version of FreeBSD to build another.
