I'm not entirely sure how xcode params are passed to the makefiles so I can't help with that. I too noticed the output was always of a wrong architecture.

When you use the makefiles directly however, you'll build a fat-library (library that includes all architectures). Include that into your project and there are no more errors.

When deploying to the appstore:
Make sure to set up a "stripping" script in your build phases. There are shell scripts for it widely available online. It's essentially just a shell script that will remove unnecessary architectures (such as simulators).
