Comment (by Algunenano):

 `libxml-2.0.pc` was apparently introduced in 2000, so it shouldn't be an
 issue to default to using it if `xml2-config` is not passed.

 This will also require changing how the libxml2 version is read to use
 `LIBXML_DOTTED_VERSION` instead. As far as I can see, that MACRO has
 existed at least since 2001.
