OK, so what about:

* On targets where gcc supports this attribute, we support it too, no warnings.
* An targets where gcc doesn't support it, we get two options.
  1. Implement it and have a warning that this is a clang extension
  2. Don't implement it and warn about an ignored attribute (like gcc does).

If a target follows 1 or 2 is mostly dependent of llvm having
implemented the naked attribute on that target.
