Bug#780640: gcc-5: merge gnat back to gcc

some comments: - please add appropriate changelog entries - don't rely on autogen during the build. I was just happy to get rid off it. I think it's fine to keep the auto generated toplevel Makefile. It doesn't change that often. I think it makes sense to build gnat out of the gcc-5
