Support building iOS focuses on using faster arm64 architecture located in the existing line up of Apple devices (as of 7/18/2014): iPhone 5s, iPad Air, and iPad mini Retina.
To be able to build for arm64, `libiPhone-lib.a` and all the `*.dll.s` must be built to consist of a 64-bit slice.
Since only architecture right now supported is armv7 (iPhone 3GS-4S, iPod touch 3-5, iPad 1-3, iPad mini 1), not the armv7s architecture that used (iPhone 5/5c, iPad 4), this needs to be thought about an delayed need.  More details on device functionality below:
