Comment (by raimue):

 The output of `pkg-config` is correct. The other libraries are not
 required for dynamic linking; only direct dependencies have to be given to
 the linker. If you add the `--static` flag, you will also see all the
 other libraries. I would recommend to use pkg-config as the output from
 xml2-config will lead to so called overlinking.
