Move the implementation of the fix from Makefile.rules to Makefile. This ensures that it is only checked on a top-level rebuild, and not in every single subdirectory. This removes some annoying messages from the build and numerous executions of config.status if the .in file changes but not substantively enough to cause the .h file to be modified by config.status. llvm-svn: 23039
