Need to use arch-linux2-cxx-opt instead of arch-linux2-cxx-debug. Also SLEPc inherits optimization options from PETSc, so does not need or allow these to be set in its call to configure.

A version of the docker file with
--enable-checks=no --enable-track=no --enable-optimize=3passed toconfigureseems like it would be useful. I've also tried to pass sensible optimization flags to mpich, sundials and petsc/slepc.I'm not sure how many docker files it's useful to keep in this repo? I also made for myself variants using openmpi (or openmpi3) and replacing sundials-2.7.0 with sundials-4.1.0. I could make PRs for those variants if anyone would find them useful.
