These tests only started to fail with the upload of python-array
0.10.2-1.  Previously, the NetCDF tests were not run.

The same failures occur on armhf, and I believe the cause is different
NaN behaviour on x86 and ARM CPUs [1].

If the problem isn't in python-xarray itself, perhaps the solution is
just to skip these failing tests on ARM.
