MKPROFILE MKSHARE, which default to `yes' unless an equivalent NOxxx
variable is defined.
* Add MKCATPAGES, which if "no" prevents catpages from being built or installed
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).
and the filesystem is full. Added ${RENAME} flag to install, which when set
to -r installs on a temporary file and then renames to the final destination.
${RENAME} is currently set to nothing in bsd.own.mk, but one can turn it
on in /etc/mk.conf.
* Allow bsd.man.mk to be included separately.
* Always include bsd.own.mk and bsd.obj.mk.
* Include bsd.man.mk and bsd.nls.mk even if NOMAN or NONLS; just turn off
building of the affected files instead.
* Require bsd.subdir.mk to be included explicitly.
(Will make appropriate changes to Makefiles shortly.)
