We've been traditionally (ab)using __FreeBSD_version to bootstrap
things in this way, without necessarily bumping __FreeBSD_version.
There are two reasons: 1) we often don't know if a particular bug
or change affects bootstrapping, so we don't always bump it.  For
example, a change in libc may cause some utility to be put to the
list of bootstrap-tools, and we don't discover it until the
version is bumped for another reason.  2) there's no harm in
bootstrapping more than necessary.
