Hm, actually this is fine I guess, just avoid `strlen` and pass literals as 
StringRefs. I would make sure the triple actually matches before you construct 
a local though, otherwise you're forcing doing it for every target, which in 
majority of the cases isn't going to be Hurd. I would still use `SmallString` 
instead of `std::string` but that's more of a nitpick.
