* * Then we dsym the global .a file
*
* For dynamic libraries we
* * Compile all source files to .o files, per architecture.
* * Then we link all .o files per architecture into a .dylib.
* * Then we lipo .dylib files into per-sdk fat .dylib, then we lipo all .dylib into a global .dylib file. So we end up with one fat .dylib for device, one fat .dylib for simulator, and one very fat .dylib for both simulator and device.
* * Finally we dsymutil the global .dylib
*
* For frameworks we
* * First we build the source files to .o files and then archive to .a files just like for static libraries.
* * Then we call mtouch to build a framework of the managed assemblies, passing the static library we just created as a gcc_flag so that it's linked in. This is done per sdk (simulator/device).
* * Finally we merge the simulator framework and the device framework into a global framework, that supports both simulator and device.
* * We dsymutil those frameworks.
