[make installworld installkernel] does not honor break at installworld

Hi All,

while installing FreeBSD at a new disk the installworld phase breaks
(see the thread "...cannot create mapper.dir: Permission denied").
However the command "make installworld installkernel" proceeds to
installkernel phase.
