Yes, I think the necessary steps are:

- Implement `xml2-config --libs --dynamic`.
- Make the libxslt build call `xml2-config --libs --dynamic` for the
  shared library. (We have to support platforms without pkg-config, so
  we can't drop support for `xml2-config`.)
- Implement `xslt-config --libs --dynamic`.
- Adjust libxslt and libexslt pkg-config files.

I'm not sure whether libxml2 should be a private dependency of libxslt (also 
what about libexslt?).
