More clearly explain portability issues with linking to a module Refine #3277 According to what I read on the internet, on OSX, both MH_BUNDLE (module) and MH_DYLIB (shared library) can be dynamically loaded using dlopen(), but it is not possible to link against MH_BUNDLE as if they were shared libraries. Metion this as an issue in the documentation. Emitting a warning, and then going on to fail during the build with mysterious errors in symbolextractor isn't very helpful, so make attempting this an error on OSX. Add a test for that.
