Yes -- at least Ubuntu < 18.04 does not install pkg-config for libxml2. 
I have not checked Debian yet, but I imagine < 8 will have the same issue.

RHEL/CentOS 6/7 look OK and I'm betting 8 is OK as well.

So, based on my limited testing thus far it is not universally 
supported, even on non-EOL distros.

Christoph, are you saying we perhaps won't need to make this change?
