Switched back to configure generating SDL_config.h

It was very confusing to have configure generate an SDL_config.h and then not have it be used when building on Mac OS X or Windows.  I'll just have to remember to use SDL_config_windows.h when building official releases that are supposed to be ABI compatible with Visual Studio.
