Of course there isn't. Legislation cannot (re)define the terms of the Constitution. The only situation where the Supreme Court would need to decide if someone was a natural born citizen, and thus define the term for Constitutional purposes, would be if a President, or President elect, were accussed of not being one, and the Court actually heard the case and made a decision. That has not happened.
However there are several court cases in which dicta indicates that "natural born citizen" requires parents who are citizens, and to have been born in the country (Perhaps with some exceptions for those born in the military or diplomatic corps).
But the Constitution does not define natural-born citizen so Congress could pass legislation laying out who is a natural-born citizen and who is not, and there would be nothing unconstitutional about it. Many people, myself included, believe that they do just that in 8 USC § 1401.

And as you know, obiter dictum are not binding under the doctrine of stare decisis.
