The simple answer is "it doesn't work like that".  If you look at the
"world" target in /usr/src/Makefile, you'll see that it in fact just
invokes a whole lot of other targets:

+ world:  hierarchy mk cleandist includes lib-tools libraries tools
+         @echo "--------------------------------------------------------------"
+         @echo " Rebuilding ${DESTDIR} The whole thing"
+         @echo "--------------------------------------------------------------"
+         @echo
+         ${MAKE} depend all install
+         cd ${.CURDIR}/share/man &&              ${MAKE} makedb

For those of you who have not delved into the dirty innards of make,
this is pretty much equivalent to

+ world:  hierarchy mk cleandist includes lib-tools libraries tools depend all install

This means "to make world, make in sequence all the targets that
follow the colon (:)".  In particular, cleandist removes everything
(this is why you can't interrupt a make world and resume where you
left off), and at the end it performs a make install.

I haven't explored all the ramifications (and people tell me there are
some which might bite me), but in my nightly cron jobs I just do a
'make depend all install'.  In your case, you might get by with a
'make depend all', leaving the 'make install' for later.
