Bug#816101: petsc: FTBFS on mipsel - timeout while running the test suite

[Drew Parsons]

As far as I can tell this build failure is just some ephemeral problem
on the build machine.  The same code built before, and builds now on
mips and other architectures. Trigger a rebuild, maybe it will work
now.

The orte/plm warning is a red herring.  All architectures have the same
problem. It's a warning not an error.  In any case, I've uploaded
v3.6.3 and invoked plm rather than orte.  Hopefully once the new
version is pushed through, the mipsel build will clear.
