math/hfst: unbreak build on DragonFly and fix libxml2 usage

lang/gcc* by default search for includes and libraries under
PREFIX/LOCALBASE unlike compilers from base. DragonFly has gcc 5.0
*in base*, so...

  checking for main in -lxml2... no
  checking for main in -lglib-2.0... no
  checking for library containing readline... no
  configure: error: readline test failed (--without-readline to disable)

libxml2 while linked in isn't actually used due to the code being
guarded by #if HAVE_LIBXML_TREE_H while

  checking for main in -lxml2... yes
  checking libxml/tree.h usability... no
  checking libxml/tree.h presence... no
  checking for libxml/tree.h... no

Also, properly track readline dependency on 11.0C which was disabled
since base r268461.
