Smpeg2 in the SDL2_mixer framework

The current SDL2_mixer OS X runtime (2.0.0 - contains an smpeg2 that links to the SDL2 framework using @executable_path/…/Frameworks instead of @rpath.

This seems to prevent my application (unix executable) to be shipped like this:

|- MyExe
|- Frameworks/
|-- SDL2.framework
|-- SDL2_mixer.framework

I could only solve this by removing that smpeg2 from the SDL2_mixer.framework I’d distribute.
