Excluding the build errors arising from code becoming incompatible with old
headers [1], the use of the latest version of Clang/LLVM for the world and
kernel is mostly hitch-free, if I
(1)remove, from the Clang installation, the headers that are already
available in /usr/include, ie.,
$ cd /home/me/my_compilers/lib/clang/3.3/include
$ rm float.h iso646.h limits.h tgmath.h and varargs.h
$ rm stdalign.h stdarg.h stdbool.h stddef.h stdint.h stdnoreturn.h
and
(2) replace -fformat-extensions with -Wno-error-format in sys/conf/kern.mk.

I had to append not only ``btxld'', but also ``ls dd cp'', to the ITOOLS
variable in Makefile.inc1.
There are apparently several things that can trigger that btxld error,
but the usual one is that your system clock is out of whack. I have
never researched it too deeply; maybe somebody else can chip in here.
I did find my system clock "out of whack", but I've already fixed that weeks
ago. I get the same error now. I don't recall getting the error when I was using the
compiler in ${WORLDTMP} [1].
Also, there are still some eye-popping warnings (-Warray-bounds,
-Wsizeof-pointer-memaccess, -Wuninitialized, -Wunsequenced) not apparently
"fixed" yet.
