The brace after " %{march=native:%<march=native 
%:local_cpu_detect(arch)" is missing.  Before committing the patch I 
retested it and fixed this typo.  So, the relevant piece of the patch 
should be
+# define MARCH_MTUNE_NATIVE_SPECS				\
+  " %{march=native:%<march=native %:local_cpu_detect(arch)}"	\
+  " %{mtune=native:%<mtune=native %:local_cpu_detect(tune)}"

This is the only difference between the patch posted in thread and patch 
committed in revision 136888.
