*sigh* Can you please check what the code is using LLVM_HOSTTRIPLE for?
Hint: it is the default target. As I said earlier and as you have
ignored, the notation of host and target in LLVM/Clang is generally
bogus and and most (if not all) notions of "host" actually mean
"target". The host system for the compiler is pretty much irrelevant
other than to get the right compiler for building and maybe the right
endianess.

I've told you already, I think deriving the default value of
LLVM_HOSTTRIPLE from $target makes more sense. What I object to is
introducing another macro and associated support code which doesn't
serve any purpose.
