This was previously discussed in 20200120204715(dot)GA73984(at)msg(dot)df7cb(dot)de which
ended without a real conclusion on what could/should be done (except that
nothing *had* to be done).

What is the situation on non-Debian/Ubuntu systems (BSD's, macOS etc etc)? Is
it worth adding pkg-config support if we still need a fallback to xml2-config?
