    scripts: handle gcc and linux in dl_cleanup script
    
    Handle gcc and linux with a special regex that set their progname with
    their major version. This way every minor version can be cleared. The
    build cleanup logic can be tweaked later to clean the entire toolchain
    and target dir with a different gcc version.
