Mike Shal 523accbeb6 Bug 1407432 - Move stl wrapper generation into moz.build; r=froydnj
This is fairly straightforward to represent as a GENERATED_FILES, though
we have to take some care to construct the outputs tuple correctly. This
script needs to run during export, and unfortunately none of the STL
headers have proper file extensions, so the 'new' header is
special-cased in the recursive make backend to serve as a marker for
running it in the correct tier.

We can't remove the stl-headers file yet because it is still used for
the system header generation.
