This was previously discussed in 20200120204715.GA73984@msg.df7cb.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?
