  New Revision: 65163

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65163

  Log:
    .travis.yml: add i686-linux tests
    
    This is a better-than-nothing compilation check that compiles
    32bit binary on a 64bit VM.
    
    Commented out are universal.i386-darwin17 biulds, which I think
    are in very low priority.
