Probably not. If I remember correctly, then host-gettext was built with
system libxz (if found) at the time. If libxz was then built afterwards and
was an older version, then executing some gettext tool would fail because
it used the wrong libxz.
We build host-gettext with --without-xz now, so I hope, this is no longer
an issue.
You can test this by installing xz devel files and then build host-gettext
and see if it uses libxz.
