[IA64] Explicitly put the unwind section into its own program-header.  This
       used to be unnecessary (probably because binutils did it for us), but
       with current binutils (e.g., v2.17.50.20070804) we won't get
       the PT_IA_64_UNWIND header without this patch which will break
       unwinding in a debugger and simulators such as Ski.
