Nothing in the patch is doing that. You're anyway using a "choice", so
the user can only decide one of gtk2, gtk3, qt4 or qt5. So this comment
in the commit log doesn't make sense.

Please use a depends on BR2_PACKAGE_LIBGTK3, so that things are
consistent with qt4 and qt5 (unless of course you switch to a select
for Qt4/Qt5 following my previous comments). But in any case, be
*consistent*.

Thanks,
