Bug#985699: xtensor: tests fail on less common architectures

[Drew Parsons]

Source: xtensor
Version: 0.22.0-3
Severity: normal
Control: forwarded -1 https://github.com/xtensor-stack/xtensor/issues/2328

xtensor tests fail on less common machine architectures, including
i386, mipsel, s390x, and others.

There seem to be two separate sets of failures. test_xnpy fails on
s390x, hppa, powerpc, ppc64, sparc64.

On i386 the failing tests are test_xbuilder, test_xfunction,
test_xreducer, test_xnan_functions.
