You can just s/NO_/WITHOUT_/g on your /etc/make.conf and leave them there.

Inconsistent use of what NO_FOO= meant.  Some places only checked if it
was set, other places required it to be set to "yes", so NO_FOO=no
might disable FOO or it might not.  The WITHOUT_* / WITH_* scheme was
chosen to be compatible with how ports works.  If WITHOUT_FOO is defined
then FOO is disabled.  If WITH_FOO is defined, then FOO is enabled.  The
WITH_FOO/WITHOUT_FOO variables end up setting an internal MK_FOO variable
to "yes" or "no" and the actual Makefiles for FOO compare MK_FOO to
"yes" to see if they should build.
