Subject: [PATCH] OS X: Fix default CMAKE_OSX_SYSROOT with deployment target

Since commit 43b74793 (OS X: Further improve default CMAKE_OSX_SYSROOT
selection, 2012-09-21) we choose a default CMAKE_OSX_SYSROOT only when
one is needed.  However, the change forgot that we require a sysroot
when a deployment target is requested.  Teach Darwin.cmake to choose a
default CMAKE_OSX_SYSROOT when CMAKE_OSX_DEPLOYMENT_TARGET is set.
