Are you referring to the imagemagick-6.6.4-8-use-xml2-config.patch? If
yes, this does not fix the problem because AC_CHECK_PROG() searches for
programmes in the $PATH and if $(HOST_DIR)/usr/bin/xml2-config is in the
path, it will find that and set xml2_config variable to $(HOST_DIR)/usr
which in turn sets LDFLAGS to -L{xml2_config}/lib
