Building a fat lib file for OpenCV

Last time we generated 4 lib files for release, debug, simulator and device. However, it's a better idea that we can use a single lib file in our project. Here is a solution, we can use lipo tool to achieve this goal. 
Universal binaries will be places in build/lib/universal folder. “build” folder is the name of the directory you’ve entered on the first stage when generating workspace in CMake. Include headers can be obtained by running install target in XCode in build/include.
Here is bash script that will merge them together:

# Create armv7 + i386 OpenCV library
 
mkdir -p build/lib/universal
