I think I've encountered things like this from before; what CMake
(always) calls the "target triple" is what autotools would call the
host triple, as I recall. Quite a few places in LLVM's build system
has terminology inherited from autotools, so it can get a bit
confusing.

You probably don't want this either. That's almost certainly an option
for when you'd be *using* your cross-compiler.

Cheers.
