Build project at https://build.opensuse.org/package/show/home:jayvdb:opentracing/python-grpcio-opentracing , where full logs can be obtained for the builds.

OK, this gets wierder.
https://build.opensuse.org/package/show/home:jayvdb:py-submit/python-grpcio-opentracing is a clone of the above build project, with more target architectures and versions of openSUSE, and the i586 build work, and the Python 3.6 builds work.
