[Vm-dev] Cog VM build failure on CentOS

[David T. Lewis]

I kicked off a couple of manual builds on this job, and it is failing
each time. I had expected this to be intermittent and "just go away".

Looking at the build history, build #54 passed, using the VM that had
been built in the prior run (build #53). Build #55 fails, running on
the VM that was build in #54. Later builds fail, still attempting to use
the VM from #54.

I am going to remove the suspect locally-built VM from #54 and force
a build using an interpreter VM. This will be build #58, which I expect
will pass. Then I'll start one more build (#59) which will use the VM
from #58 and see what happens. If it fails, then we may have detected
a real bug. Stay tuned ...
