Please remember Ubuntu 18 has reached "normal" EOL in April already:

https://ubuntu.com/blog/ubuntu-18-04-eol-for-devices

And it ships with Glibc 2.27
(Even debian buster has 2.28…)

If we want to support older GLIBCen, we have to do strange dances:
- for example, explicitly marking symbols to use "old" versoines ones
  https://web.archive.org/web/20160107032111/http://www.trevorpounds.com/blog/?p=103
  (this seems excessive)
  (but pepople seem to have managed that: https://stackoverflow.com/a/69139182 )
- link statically, but that is, imho a Very Bad Idea™
- Kill the version info and cross fingers: https://stackoverflow.com/a/73388939
- Build on ubuntu 18.04. I don't know whether github still has this for runners…


it's messy
