Make explicit the minimum numpy version 1.11

Having numpy 1.10.* as build requirement causes to not generate any build at all.

Conda-smithy has explicitly numpy>=1.11 as requirement and skips any incompatible build. See https://github.com/conda-forge/conda-smithy/blob/master/conda_smithy/configure_feedstock.py#L640

It would be good to have a warning or something that tells that the build matrix couldn’t be generated due to incompatible dependencies.

@isuruf pointed out the missing numpy >=1.10 run requirement.

After fixing that this the rerender changes:

I notice the major change is removing CONDA_NPY=111. Does that means it uses the latest numpy version for the build? I will test it.

[rmax]

So, when using as build requirement numpy 1.10.* the build config does not include the CONDA_NPY envvar, however the build uses numpy 1.10.4 as expected.

The bug we had was not including numpy as run requirement.
