Comment:
For xfce4 stuff, it's defined by `XDT_I18N` from `xfce4-dev-tools`, it can be fixed by `--with-locales-dir=/usr/share/locale`.
For other stuffs, I don't think we can fix in general, except patching `/usr/share/aclocal/glib-gettext.m4` from `glib-devel` and run `autoreconf -fi` for all problematic packages.
