Convert usr.sbin to LIBADD
Reduce overlinking

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

Let bsd.prog.mk set SRCS and MAN to their default values.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

style.Makefile(5)

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Remove GCC'isms in CFLAGS.

Improve mkctm.c so we can use it, and start using it.
This should help quite a bit on the load. Notice that
some minor changes in config files will be needed.
Contact me for details.

Commit the right version of mkCTM, <:-)

Update to current reality.
mkctm.c can replace the guts of mkCTM if anybody feels like it...
