Hi,

Package pyresample FTBFS on mips* with following error:
> ======================================================================
> FAIL: test_custom_uncert (pyresample.test.test_kd_tree.Test)
> ----------------------------------------------------------------------
> Traceback (most recent call last):
>   File "/«PKGBUILDDIR»/pyresample/test/test_kd_tree.py", line 102, in test_custom_uncert
>     len(w) != 1, 'Failed to create neighbour warning')
> AssertionError: Failed to create neighbour warning
>
> ======================================================================
> FAIL: test_gauss_uncert (pyresample.test.test_kd_tree.Test)

Tests are failing because there are more warnings than expected on mips*.
With added debug prints the following warnings are raised:
> DBG: test_custom_uncert w[0] = {message : UserWarning('Searching for 8 neighbours in 3 data points',), category : 'UserWarning', filename : '/build/pyresample-X1AqqR/pyresample-1.2.5/pyresample/kd_tree.py', lineno : 314, line : None}
> DBG: test_custom_uncert w[1] = {message : RuntimeWarning('invalid value encountered in multiply',), category : 'RuntimeWarning', filename : '/build/pyresample-X1AqqR/pyresample-1.2.5/pyresample/kd_tree.py', lineno : 834, line : None}

> DBG: test_gauss_uncert w[1] = {message : RuntimeWarning('invalid value encountered in multiply',), category : 'RuntimeWarning', filename : '/build/pyresample-X1AqqR/pyresample-1.2.5/pyresample/kd_tree.py', lineno : 834, line : None}

Tests are fixed by changing the asserts to handle more warnings than expected.
This solution was proposed upstream.

With attached patch I was able to build pyresample successfully for mips*.

Thanks,
Daniel
