 This one looks nice :-)

 I'm not sure about adding a FLAGS section.  It would seem a bit
 inappropriate to keep descriptions of some NO_XXX options in build(7),
 others in make.conf(5) and leave some more documented only in
 `src/Makefile.inc1'.
 
 IMHO, we should document make.conf variables in make.conf(5) (i.e. the
 NO_DYNAMICROOT, NO_GAMES and NO_MAN options listed above), and only
 document in build(7) the following:
 
     -DNO_CLEANDIR run ${MAKE} clean, instead of ${MAKE} cleandir
     -DNO_CLEAN do not clean at all
     -DNO_KERNELCONFIG do not run config in ${MAKE} buildkernel
     -DNO_KERNELCLEAN do not run ${MAKE} clean in ${MAKE} buildkernel
     -DNO_KERNELDEPEND do not run ${MAKE} depend in ${MAKE} buildkernel
     -DNO_PORTSUPDATE do not update ports in ${MAKE} update
     -DNO_DOCUPDATE do not update doc in ${MAKE} update
     LOCAL_DIRS="list of dirs" to add additional dirs to the SUBDIR list
     TARGET_ARCH="arch" to crossbuild world to a different arch
