I don't agree with this. This is redundant. Why not put RUN_TESTS=1 on
an already exiting builds instead of adding two new builds like you
are doing here?
A build without the tests takes ~7 minutes, with the tests it
increases to ~9 minutes. These two new builds add ~18 minutes of build
time to the entire travis build time. We could use this ~18 minutes
instead to run the tests on 6 to 9 already existing builds since they
take 2 to 3 extra minutes on each one.
