+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch.  Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?
