[Ves] Build for armv7s and arm64

[Casey Goodlett]

Jon,

I have no tried arm64 so I do not know where the problem is.  A couple of
thoughts to try:

You might try increasing the iphoneos-version-min to 7.0 maybe thats needed
to support arm64.  This stackoverflow entry
http://stackoverflow.com/questions/18913906/xcode-5-and-ios-7-architecture-and-valid-architectures
seems
to indicate you need to set a minimum of 6.0 for arm64 support.

If you can disable libarchive and libcurl for the arm64 test we could
eliminate those as variables.

Try a serial build "make -j1" so that the error is the last output.

Let us know what you find out
