5608fd23c2 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.

864c53ead8 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.

c640c5f4d9 Autoconf would have created a symlink from conf/autofs/autofs_default.h 
to autoamu_autofs_prot.h.  It is easier to just create shell header within
the Bmake framework.

For now it's a stub - fill out when we know our Autofs direction.
