[vpp-dev] Multiple vpp-verify-master-ubuntu1604 failures in 'make test'

[Dave Wallace]

Folks,

The following patches all failed to verify due to the same failure 
signature in 'make test':

   https://gerrit.fd.io/r/6751
   https://jenkins.fd.io/job/vpp-verify-master-ubuntu1604/5499/console

   https://gerrit.fd.io/r/6752
   https://jenkins.fd.io/job/vpp-verify-master-ubuntu1604/5504/console

   https://gerrit.fd.io/r/6662
   https://jenkins.fd.io/job/vpp-verify-master-ubuntu1604/5508/console

All other verify jobs passed in all cases. For 6751, there were no code 
changes in the patch set.

Is this a known failure signature?

Thanks,
-daw-
