+         need full debugging information (like kgdb or systemtap) won't
+         be happy. But if you merely need debugging information to
+         resolve line numbers there is no loss. Advantage is that
+         build directory object sizes shrink dramatically over a full
+         DEBUG_INFO build and compile times are reduced too.
