    ct-ng lab updates for Ubuntu 18.04
    
    - A more recent version of crosstool-ng is needed, otherwise
      you end up trying to build gcc 6.3 with gcc 7.3, which is stricter
      and then fails.
    
    - You need to use ./bootstrap instead of autoreconf
    
    - "make install" doesn't work anymore with "--enable-local" in configure
      but is not needed anyway.
