You might try this. Put this at the *top* of your file:

--8<---------------cut here---------------start------------->8---

#+PROPERTY: header-args :eval never-export

#+NAME: tangle file
#+BEGIN_SRC emacs-lisp :eval yes :exports results
(org-babel-tangle)
#+END_SRC

--8<---------------cut here---------------start------------->8---

Type C-c C-c on the property line to refresh it.

Now export. Type 'y' in reply to the query to eval the `tangle file' src 
block and again to the `discard edits' query.

Even exporting to a buffer should be fine. You do not really want the 
exported document, you just want to force the inclusions to take place and 
then run that src block.

This should work, because `org-export-as' will expand all the include's 
before running babel. If the above block runs before any others, then the 
:tangle headers will still be in place.

In fact you could create a separate file, place all the above in it and 
add one line at the bottom to include the top level org file you want to 
tangle from. Then export that.

HTH,
