Description of problem:
Once a RHEL 8 brew build is added to errata, it is exported to git.centos.org and built for CentOS Stream 8.  In bug 1831941, it was requested to backport the --runstatedir flag to autoconf.  Here is a timeline of what happened next.

2021-01-19 implemented in autoconf-2.69-28.el8 [0]
2021-01-20 added to advisory RHBA-2021:68474 [1]
2021-01-21 exported to the c8s branch on git.centos.org [2]
2021-01-21 built for CentOS Stream 8 [3]
2021-01-27 shipped for CentOS Stream 8 in compose CentOS-Stream-8-20210127.n.0 [4]
2021-03-19 reverted in dist-git [5]
2021-03-22 dropped from advisory RHBA-2021:68474 [6]

We are now in the situation where CentOS shipped an NVR to users that will not go into RHEL.  I've taken care of pulling that NVR from our mirrors, but users who've already installed that package need an upgrade path solution to get back onto the correct package.  Please bump the release to 29 to accomplish this.
