I realize this is a month late -- but this is what the FreeBSD ``make
world'' does.  First the build-tools and build-libs are built and
installed into a tree rooted /usr/obj/tmp/.  Then those tools are used to
build the entire system.  This way one can always go from FreeBSD version
X to version X+1.  The only limitation is the requirement that the person
updates the system to the latest -STABLE (release) in the X series.
