    travis: use `set -e` as a workaround for travis not aborting pipelines
    
    This should be the behaviour by default, but it seems Travis has not solved
    this issue yet:
    https://github.com/travis-ci/travis-ci/issues/1066
    
    Before this, it could happen that autogen.sh failed (because of some
    missing dependency) but still try to build after that.
