These failures are not reproducible on other RHEL-8 supported architectures.
Moreover, the same testcases were running successfully on previous golang-1.10.3-18.module+el8+2240+384d32ea.

Version-Release number of selected component (if applicable):
golang-1.11.2-1.module+el8+2368+e260b36a.aarch64
RHEL-8.0-20181204.0

Steps to Reproduce:
1. go tool dist test -rebuild -v -v -v -k
