Allows successful build of arm64 libraries using GYP_DEFINES="OS=ios target_arch=arm64 target_subarch=arm64". Note that not all libraries will be NEON optimized (eg common_audio), however most importantly libvpx will be. WEBRTC_ARCH_ARM needs to be defined so that libvpx doesn't post-process, which is significantly detrimental to performance.
