[Ves] Build for armv7s and arm64

Weird.  Somehow I have been successfully building with xcode 5 and the ios
7 sdk without this problem.

Maybe I have some old headers on my system that were not removed during the
upgrade?

I dug a bit further and for the device toolchain configuration on my build
there is no gcc or g++ in the iPhoneOS system root (although there is in
the simulator system root).  As a result the superbuild falls back to the
system level compiler.  These seems to compile ok when given the proper
arch and min iphoneos version commands.  I wonder if for newer xcode we
should use the system compiler and configure architecture, sysroot, and
min-iphoneos-version options for device and simulator builds.

I might try a clean uninstall and reinstall of xcode to get myself back to
a clean slate.
