note that 'make world' already doesn't work unless you're using DESTDIR
(or you set a special make knob) so it shouldn't be documented as a way
of upgrading the system in general, e.g. in build(7).

afaik, every invocation of 'make world' can be trivially replaced by
'make buildworld installworld', but there may be some argument for
keeping it around for people who use it to build jails, for the sake
of muscle memory.
