[Wheel-builders] BLAS/LAPACK for manylinux1 wheels

[Olivier Grisel]

If we can run all the scipy stack tests (say for instance numpy,
scipy, pandas, scikit-learn, scikit-image, statsmodel) with the
openblas built on the manylinux1 docker image using Matthew's script
on a variety of boxes, then I am fine with using openblas. If running
the tests reveals unresolved bugs / crashes in OpenBLAS, then I think
we should go with atlas in the short term and re-examine that decision
in a couple of months.

Matthew, FYI to run docker in travis, you just need to enable the
docker service in .travis.yml:

services:
  - docker

as done in: https://github.com/pypa/manylinux/blob/master/.travis.yml#L3

Then you can use the docker command line to run or build containers
within a travis job.

Let me know if you extend your scripts to build and upload wheels for
the missing projects (scikit-learn, scikit-image, statsmodel and
maybe others). I can run the tests on some cloud VMs and a couple of
old and newer workstations at my work.
