b791fbe630 META MODE: Don't create .meta files when symlinking sources into the obj directory.
Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file.  There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

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.

a7449e3cca Since clang 3.2 now has an option to suppress warnings about implicitly
promoted K&R parameters, remove the workarounds added for sendmail
components in r228558.

07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

ff3879a34a Unfortunately, clang gives warnings about sendmail code that cannot be
turned off yet.  Since this is contrib code, and we don't really care
about the warnings, just turn make them non-fatal for now.

1100c00131 Make WARNS=6 the default for libexec/.
Just like bin/ and sbin/, I think setting WARNS to the highest value
possible will make it more attractive for people to fix warnings.

- The WARNS variable is set in the Makefile in the directory of the
  application itself, making it more likely that it will be removed out
  of curiosity to see what happens.
- New applications will most likely build with WARNS=6 out of the box,
  because the author would more likely fix the warnings during
  development than lower WARNS.

Unfortunately almost all apps in libexec require a lowered value of
WARNS.

88c75941e6 The rest of the changes needed to support the new version of sendmail (8.11.0).
Beyond changes to the build system, this includes fixing up the sample
freebsd.mc configuration for changes in defaults and syntax, removing
outdated documentation, and updating the release notes.
