+          If you say Y here gcc is instructed to generate less debugging
+          information for structure types. This means that tools that
+          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.
+          Only works with newer gcc versions.
