I applied the following patch on top of yours, which adds

     <li>DWARF4 is now the default when generating DWARF debug information.
-      When -g is used on a platform that uses DWARF debugging information,
-      GCC will now default to -gdwarf-4 -fno-debug-types-section.

       GDB 7.5, Valgrind 3.8.0 and elfutils 0.154 debug information consumers
       support DWARF4 by default. Before GCC 4.8 the default version used
-      was DWARF2. To make GCC 4.8 generate an older DWARF version use -g
-      together with -gdwarf-2 or -gdwarf-3. The default for Darwin and
-      VxWorks is still -gdwarf-2 -gstrict-dwarf.
