Those QA failures are probable a Volk issue. Try running volk_profile
after you run 'make install'. If a given kernel fails for an
architecture, it will be disabled. Once volk_profile completes (it can
take a while), try rerunning 'make test'. If it still fails, run
'ctest -V -R volk' and send us the output.

What's your processor?
