Explicitly setting WITHOUT_KERBEROS implies WITHOUT_KERBEROS_SUPPORT,
but previously other cases that forced KERBEROS off (such as
WITHOUT_CRYPT) did not also set KERBEROS_SUPPORT off. Because the
_SUPPORT dependent options (KERBEROS/KERBEROS_SUPPORT) are processed
before other dependencies (CRYPT/KERBEROS) it's not easy to make this
happen automatically. Instead just explicitly set KERBEROS_SUPPORT
off where we set KERBEROS off.

hard use floating point hardware, pass registers to functions in
floating point registers.
softfp use floating point hardware, but pass registers to functions
in integer registers.
soft do floating point calcuations without using floating point
hardware. Pass arguments in integer registers.
FreeBSD 11 and newer assumes hard. 10 and earlier assumed softfp. We have no
real support, at the moment, for soft. It's untested, though, if softfp still
works.
Add a note here since this is a whack-a-doodle combination relative to all other
platforms.
softfp is likely to go away in the future because it was retained for people
using FreeBSD 10 + armv6 needing to transition more slowly from softfp -> hard
than the project. It likely is no longer needed, and may be getting in the
way of people needing 'soft' support.
Only sparc64 did not enable LLVM_LIBUNWIND. After r356513 LLVM_LIBUNWIND
should at least build on sparc64. The old DWARF unwinder will be removed
along with GCC 4.2.1 in the near future, so switch sparc64 to use LLVM's
unwinder in advance of the removal. Someone with access to the obsolete
sparc64 hardware supported by FreeBSD will have to test, and investigate
any failures. I will gladly help, but I don't have any suitable hardware
myself.

This re-enables building the googletest suite by default on mips and instead
specifically doesn't build fusefs tests for mips+clang builds. clang will
easily spent >= 1.5 hours compiling a single file due to a bug in
optimization (see LLVM PR 43263), so turn these off for now while that's
hashed out.
GCC builds are unaffected and build the fusefs tests as-is. Clang builds
only happen by early adopters attempting to hash out the remaining issues.
The comment has been updated to reflect its new position and use less strong
wording about imposing on people.

Extend r356379 to include 32-bit mips and sparc64. Using a decade-old
binutils linker with a contemporary compiler (either Clang or GCC) is
a combination unlikely to be used by anyone else, and it's not going
to be a good use of our time investigating and addressing any issues
that arise. Expect that all architectures newly migrated to external
GCC will also use external binutils.
After GCC was disabled by default in r356367, mips and sparc64 started
relying external GCC. However, the in-tree Binutils ld 2.17.50 is not
compatible with GCC for some mips64 targets, so turn off
BINUTILS_BOOTSTRAP and rely on external binutils (linker) as well.

More MACHINE_CPUARCH/MACHINE_ARCH cases enable these options than
disable them, and several of them have work in progress to switch over.
Thus, invert the sense of the test and list cases not using LLD as the
exceptions.
There were a few special cases for arm v5, such as disabling LLDB due to
the lack of 64-bit atomic operations. Now that arm has been retired (as
of r356263) we can simplify the options logic somewhat.
We use the BSDL devicetree compiler as long as we have a C++11 compiler.
dtc is not needed as a build tool on the platforms that are still using
GCC 4.2.1 (and it is being disabled very soon, anyhow).

PowerPC switched to LLVM_LIBUNWIND along with the switch to Clang/LLVM
in r356111. This leaves only 32-bit Arm and sparc64 not using LLVM's
unwinder, so switch the sense to opt-out.
I elected to list the individual arm MACHINE_ARCHs so future changes
are more clear if LLVM_LIBUNWIND is enabled for one or two but not all
32-bit Arm targets (see PR 233664).
After PowerPC switched in r356111, the list of targets using LLVM as the
default toolchain is much longer than those not using it. Switch the
sense of the test to exclude those not using LLVM.
Targets not using LLVM is currently mips, riscv5, and sparc64; work is
in progress to migrate the first two to LLVM.
This enables LLVM as the default compiler for powerpc, powerpc64, and
powerpcspe, as well as LLD as the default linker for powerpc64.
LLD is not yet ready for prime time for powerpc and powerpcspe, but work is
continuing on it.

Summary:
This patch is to support ongoing work for replacing "GCC/BFD" by "CLANG/LLD" on
target PowerPC64 [1], by proposing a way to specify and/or locate a secondary
ld.bfd linker.
This is necessary as LLD currently doesn't support PowerPC 32 bits, so we keep
using BFD for the 32 bit stuff on PowePC64(LIB32 compatibility and
STAND/slof/loader.)
- creates LD_BFD variable pointing to ld.bfd
- use LD_BFD as linker for LIB32/compat
- Default behavior for other platforms aren't changed.

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.
flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.
linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.
luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.
src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.
