arm64, ppc64el and i386 are fast architectures. > I will enable the verbose debugging (#896861).

I have built openmpi_3.0.1-9 on plummer (ppc64el porterbox) 20 times in a loop without a failure. It would be good to fix this but with such a low failure rate I'm downgrading this to allow migration to testing. Emilio
