Users should use "MKxxx=no" instead of "NOxxx=" in /etc/mk.conf, because
this allows easy override on the make(1) command line (e.g 'make MKSHARE=yes'
to override MKSHARE=no in /etc/mk.conf).
stuff duplication by expressing it in terms of <bsd.files.mk>. Allow for
multiple inclusion of <bsd.files.mk> by clearing ${FILES} at the end, and
using FILES+= rather than FILES= in <bsd.info.mk>.
