I expect that we'll actually have a different `__config_site` when having a target triple that implied a freestanding platform. I don't think it makes any sense to support passing `-ffreestanding` on hosted platforms. When we have a target triple that implies a freestanding platform, we shouldn't care whether the flag is passed either, since we'll only provide what the platform wants us to support (which may be more than strict freestanding).

If that's so, it may be a good idea to freeze this pull request temporarily.
