Add some rules to more closely match what illumos does when an address
resolves to multiple symbols:
- prefer non-local symbols
- prefer symbols with fewer leading underscores and no leading '$'
Add some regression tests to verify these rules.
* Wrongly matches strings that are shorter than the pattern
* Fails to match negative character sets
* Fails to match character sets that aren't at the end of the pattern
* Fails to match character ranges

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Add notes to each of these that specifically state that results are
undefined if the strings overlap. In the case of memcpy, we document
the overlapping behavior on FreeBSD (pre-existing). For str*, it is
left unspecified, however, since the default (and x86) implementations
do not handle overlapping strings properly.

syslog in libc secretly reconnects to the daemon.
Another issue is that we don't have any information from openlog(3) if we
succeeded to open log or not so we don't know if we are ready
to enter cabability mode.
Because all of that we decided we need a syslog service for Caspser.

We started out having Linux compatible libefivar interfaces. This was
in anticipation of porting the GPL'd efibootmgr to FreeBSD via a
port. However, since we need that functionality in the base, that port
isn't going to happened. It also appears that efivar is a private
library that's not used much outside a command line util and
efibootmgr. Reduce compatibility with the Linux version a little by
removing the mode parameter to efi_set_variable (which was unused on
FreeBSD, and not set to something useful in the code we'd
written). Also remove some efi error routines that were never
implemented and existed only to placate early GPL efibootmgr porting
experiments.

:U:Mfoo expands to :Mfoo, apparently. Explicit check for CPUTYPE being

armhf.
Tested, somewhat. Unfortunately recent changes appear to have affected
cross-builds where it no longer works, per my tests after universe12a being
upgraded from 07/2017 to 11/2017 sources (DESTDIR isn't being used in WORLDTMP;

CPUTYPE (apparently) isn't defined in non-cross-builds, which caused
arm/armv[67] hosted/targeted builds to fail when evaluating CPUTYPE.
Add the :U modifier to CPUTYPE so it evaluates to "". This allows armv[67] to
get past the conditional successfully.

- MK_PROFILE is controlled in bsd.opts.mk, which is pulled in via bsd.own.mk,
which is pulled in via bsd.init.mk . All upstream Makefiles which build off
of this one use bsd.init.mk.

- Define TARGET_CPUARCH and use in libclang_rt as the basis for CRTARCH
When cross-compiling, the wrong architecture was being embedded in the
libclang_rt binary filenames. It should be based on TARGET_ARCH (target), not
MACHINE_ARCH (host).
If TARGET_ARCH isn't defined (host-builds), fallback to MACHINE_ARCH.
- Define CRTARCH to armhf when TARGET/TARGET_ARCH are set to arm/armv[67]
TARGET_ABI/TARGET_CPU in Makefile.inc1 sets the ABI to gnueabihf, which
affects the clang lookup path per `getArchNameForCompilerRTLib(..)` in
contrib/llvm/tools/clang/lib/Driver/ToolChain.cpp, so chase clang and
Linux's assumed naming convention for hard-float arm architectures.
CROSSENV (in Makefile.inc1) sets CPUTYPE/MACHINE(_ARCH)? to the
TARGET*-relevant values when building the `libraries` target, so test
those variables instead.
- Add OLD_FILES/OLD_LIBS entries for TARGET/TARGET_ARCH == arm/armv[67]. This
impacts only arm/armv6 and arm/armv7.
