provide commands required to create the syslog log files used by this config
don't need to rotate /var/cron/log, as all.debug doesn't use it
add a newsyslog.conf that matches the all.debug.
Set NOxxx= before <bsd.own.mk> is pulled in (even indirectly).Otherwise the appropriate MKxxx=no won't be defined .
MKfoo=no -> NOfoo
example syslogd(8) config files (to be installed as /etc/syslog.conf): all.debug - each facility gets logged to its own file
