Ruslan Ermilov 2bdaf7e81c Don't include bsd.own.mk from sys.mk, this makes it impossible
to use ``.if defined()'' inside bsd.own.mk to test for defines
in individual makefiles.  For example, setting DEBUG_FLAGS in
Makefile didn't take the desired effect on the STRIP assignment.

Added bsd.init.mk (like in NetBSD) that handles the inclusion
of ../Makefile.inc and bsd.own.mk from all bsd.*.mk files that
"build something".

Back out bsd.own.mk,v 1.15: moved OBJFORMAT initialization back
to sys.mk (several source tree makefiles want to check it early)
and removed MACHINE_ARCH initialization (it's hard to see from
looking at the commitlogs what the problem was at the time, but
now it serves no purpose).

Prohibit the direct inclusion of bsd.man.mk and bsd.libnames.mk.

Protect bsd.obj.mk from repetitive inclusion.  Prohibiting the
direct inclusion of bsd.obj.mk might be a good idea too.

# $FreeBSD$
#
# The include file <bsd.obj.mk> handles creating the 'obj' directory
# and cleaning up object files, etc.
#
# Under construction: it also contains the _SUBDIR target (which is used
# by most `mk' files to recurse into subdirectories) and defaults for the
# cleandepend, depend and tags targets. It may eventually be merged with
# with bsd.subdir.mk.
#
# +++ variables +++
#
# CLEANDIRS Additional directories to remove for the clean target.
#
# CLEANFILES Additional files to remove for the clean target.
#
# MAKEOBJDIR A pathname for the directory where the targets
# are built. Note: MAKEOBJDIR is an *enviroment* variable
# and works properly only if set as an enviroment variable,
# not as a global or command line variable!
#
# E.g. use `env MAKEOBJDIR=temp-obj make'
#
# MAKEOBJDIRPREFIX Specifies somewhere other than /usr/obj to root the object
# tree. Note: MAKEOBJDIRPREFIX is an *enviroment* variable
# and works properly only if set as an enviroment variable,
# not as a global or command line variable!
#
# E.g. use `env MAKEOBJDIRPREFIX=/somewhere/obj make'
#
# NOOBJ Do not create object directories. This should not be set
# if anything is built.
#
# +++ targets +++
#
# clean:
# remove ${CLEANFILES}; remove ${CLEANDIRS} and all contents.
#
# cleandir:
# remove the build directory (and all its contents) created by obj
#
# obj:
# create build directory.
