[Ves] Build for armv7s and arm64

[Jon Chmura]

Casey,

Thanks for the quick reply.  I wasn’t able to build with arm64.  I checked out a new copy of VES.  Modified to add arm64 (see git diff)

 set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -miphoneos-version-min=5.0 -fvisibility=hidden -fvisibility

The build failed but I didn’t see any useful error messages.  Maybe an issue with libarchive...
