[Wheel-builders] [manylinux] how to build numpy/scipy wheels for x86

[Olivier Grisel]

I can reproduce the exact same error on a fresh ubuntu/trusty32
vagrant box with numpy 1.11.0 and scipy 0.17.0 built from source with
system Python 3.4.3, libopenblas-dev 0.2.8-6ubuntu1, liblapack-dev
3.5.0-2ubuntu1 and gfortran 4.8.2-1ubuntu6.

https://atlas.hashicorp.com/ubuntu/boxes/trusty32

```
mkdir trusty32 && cd trusty32
vagrant init ubuntu/trusty32
# edit Vagrantfile to set virtualbox VM memory to 4096
vagrant up --provider virtualbox
vagrant ssh
```

So this is not related to the manylinux packaging itself.
