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.
when certain .mk files include other .mk files. This will remove the
need for multiple include protection in some other makefiles around the
tree (and helps some elf conditionals).
bsd.obj.mk instead of bsd.dep.mk for defining the _SUBDIR target
and a default tags target. Abuse bsd.obj.mk for defining default
cleandepend and depend targets.
latin1 looks very ugly on Russian screens/printers and users should
be able to print/view handbook first without inner knowledge of
bsd.sgml.mk tuning.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Add some comments for variables and targets.
Include <bsd.obj.mk>, remove targets obj, clean, cleandir.
Replace ${MAN*} with ${DOC*} variables.
Use a .for loop for undefined targets
FORMATS can be defined as an empty string to suppress generation or
installation of any files. Previously setting it to "null" had that
effects.
Now uses MANOWN, MANGRP and MANMODE for installation instead of BINOWN,
BINGRP and BINMODE.
