e48a052e - Fix link error on s390x (#101000)

Fix link error on s390x (#101000) When I got the main branch and picked up #99872, I got the following link error. The root cause is that method definitions in the header file will generate multiple instantiations for the same method signature. This PR fixes the link error by avoiding to generate multiple instantiations. ``` % python setup.py develop ...
