fix bootstrapped modules in framework builds, take 2

the borrowing of headers always happens from "proper" modules which are
actually built as frameworks if so requested. that means that even
though the borrowing module itself never is a framework, it needs a
framework path and include paths that point into frameworks.

amends 20c7ab44.
