1.19: 1 bit non-determinism in kube-scheduler.1

[bmwiedemann]

What happened:
50% of builds have a different man page content

What you expected to happen:
It should be possible to get bit-identical build results - might need a patch similar to #68983 - @dims knows these things.

How to reproduce it (as minimally and precisely as possible):
build kubernetes1.19 openSUSE package a few times and compare results. e.g. with my rbk script

Anything else we need to know?:

Environment:

• OS: openSUSE-Tumbleweed 20200906

While working on reproducible builds for openSUSE, I found that
when building the kubernetes1.19 package, there was sometimes such a difference between builds:
