Remove $FreeBSD$: one-line sh pattern

pkgbase: Create a FreeBSD-kerberos package

This allows users to install or not kerberos related utilities
and libs.

Revert r267233 for now. PIE support needs to be reworked.

1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.

This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

This is sort of an MFS. Peter made these changes to the RELENG_*
branches but missed HEAD. This patch extends his a little bit,
setting it up via the Makefiles so that adding _FREEFALL_CONFIG
to /etc/make.conf is the only thing needed to cluster-ize things
(current setup also requires overriding CFLAGS).

From Peter's commit to the RELENG_* branches:
> Add the freebsd.org custer's source modifications under #ifdefs to aid
> keeping things in sync. For ksu:
> * install suid-root by default
> * don't fall back to asking for a unix password (ie: be pure kerberos)
> * allow custom user instances for things like www and not just root

The Makefile tweaks will be MFC-ed, the rest is already done.

Start the dreaded NOFOO -> NO_FOO conversion.

Introduce the PRECIOUSPROG knob in bsd.prog.mk, similar
to PRECIOUSLIB from bsd.lib.mk. The side effect of this
is making installing the world under jail(8) possible by
using another knob, NOFSCHG.
