    Fix README files and remove stale config.guess and config.sub
    
    README.Unix.txt and README.Windows.txt (MinGW, MSYS) instructed to
    execute `NOCONFIGURE=1 ./autogen.sh` which is no longer necessary
    (a simple `autoconf` does the job).
    
    Remove files misc/config.guess and misc/config.sub because they are
    no longer needed: these files are now in th FLTK root directory
    available. Remove all references to these files.
    
    Fix .gitattributes accordingly. Also exclude the .github folder
    from exports, for instance when creating distribution tarballs.
