installed by "make install") without setting of BUILD. All cases where BUILD
is already set are unchanged from the old behavior.
"make all install" is now practically equivalent to "make BUILD= all install",
but without actually setting build.
Fixes pr's 8313, 3894.
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.)
