[lsh123]

The 1.6.3 was released in 2020 and it's probably time to upgrade.

Here's the workaround we use for libxml2.

I'm not so familiar with automake, but do you think it will be a major headache for many projects if we keep using the version Ubuntu ships? I think finding another source for it will be a maintenance burden we wouldn't want to take on without good reason (there is also no end to how many build systems we might do this for :-)

I think it should be safe to update Autotools with the hack above, but the base image is getting a bit old now, see #11835.
