6fbb928f93 For arm targets, place ABI at the end of the target triple 
For some reason, we have been inserting the ABI specification into the
middle of the target triple, when building LLVM, like so:

    armv6-gnueabi-freebsd12.0

This is the wrong way around.  LLVM even auto-canonicalizes it to:

    armv6--freebsd12.0-gnueabi

Let's do this the right way in llvm.build.mk instead.  While here,
define a proper VENDOR macro which can be overridden easily.

06180ca3d8 Turn off llvm/clang's ENABLE_BACKTRACES setting, since it never worked

48f45a5a5b Add -mlong-calls also to LLVM's STATIC_CFLAGS on ARM 
-mlong-calls was set only in STATIC_CXXFLAGS, but there are some .c
source files in LLVM which also need -mlong-calls.

Unfortunately this is not sufficient to fix linking lldb on ARM,
because LLVM-generated calls to __aeabi_read_tp do not honour the
-mlong-calls flag.  See LLVM PR31769 for details.

a52f519c26 Also apply WITH_LLD_AS_LD to build tools 
Previously WITH_LLD_AS_LD installed LLD as /usr/bin/ld in the target
system, but still used the GNU BFD ld to link the binaries in that
target. LLD 4.0.0 can link the FreeBSD/amd64 world and kernel so use
LLD as the build-time linker as well when the knob is set.

Move llvm-objdump from CLANG_EXTRAS to installed by default

We currently install three tools from binutils 2.17.50: as, ld, and
objdump. Work is underway to migrate to a permissively-licensed
tool-chain, with one goal being the retirement of binutils 2.17.50.

LLVM's llvm-objdump is intended to be compatible with GNU objdump
although it is currently missing some options and may have formatting
differences. Enable it by default for testing and further investigation.
It may later be changed to install as /usr/bin/objdump, it becomes a
fully viable replacement.
