Is this for users or scripts?

For users, it would be better to squeeze this into some existing help/version option, like clang -v or clang --help.  Unfortunately, I think the format of clang -v might be tightly constrained by existing scripts to follow GCC's lead, which is why we have nonsense things like a threading model in there.

For scripts, rather than making a new top-level option (unless there's precedent for this one in particular), it would be better to introduce a general querying option and just make this the first parameter for it.  e.g.
  clang --show targets
