    opensaf: Add -latomic to LDFLAGS
    
    * Add "-Wl,--as-needed -latomic -Wl,--no-as-needed"
      to LDFLAGS to let the libatomic handled automatically
      if required to fix below build error as atomic
      operations on some arch such as x86 are supplied by
      the compiler. For other arch which lacks the instructions,
      a standardized external call provided by external library
      libatomic will be made to perform the operation.
