I think we should find a way to remove this long list of test names in
the build file. The list of available tests is built up dynamically
inside the test binary, so I'm wondering if we can add to the binary an
"all" option to run each autotest straight after each other?

This should be moved up beside the other dependencies

A note for the future: since much of this looks similar to that in
testpmd we should look to see if we can find a way to easily consolidate
these build commands inside a foreach loop like is done for the libs,
drivers and examples.
