Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Convert usr.sbin to LIBADD
Reduce overlinking

The last big commit: let usr.sbin/ use WARNS=6 by default.

Enable building of OpenBSM command line tools:

- audit(8) - audit subsystem management tool
- auditd(8) - audit trail and subsystem management daemon
- auditreduce(1) - audit trail reduction tool
- praudit(1) - audit trail printing tool

Could probably use a NO_AUDIT make.conf flag.
