Subject: [PATCH] macx-ios-clang: only provide default LaunchScreen.xib if
 using Xcode 6
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If using an older version of Xcode, Xcode will sometimes complain
that LaunchScreen.xib uses auto layout while the project at
the same time has deployment target set to 5.0 (where auto layout
is not supported).
This is a bug in Xcode really, since LaunchScreen.xib will only be
used when running on iOS 7 (otherwise a LaunchImage will be used).
This has been fixed in Xcode 6.

This patch adds a check for this early on.
