xtensor builds with -march=native. I didn't check if there are code paths that
work with the default baseline on amd64. If there isn't such a code path, then
it is another bug report.
However building -march=native is not deterministic, you never can say if the
package works on your machine or, because it's just dependent on the buildd.
From my point of view, no package should be built with -march=native.
At least GCC has -march=x86-64-v[1-4] for such settings, so please use that
instead, and look for other appropriate settings on the other architectures.

xtensor is a header-only library. -march=native is used when building
tests.
The end-user would be sensible to use -march=native in their own builds,
so it's appropriate to test it also in debian tests.
