As announced in #1148038, new upstream releases of WebKitGTK no longer
support big-endian architectures.

meta-gnome currently pulls in some WebKitGTK-dependent packages, notably
evolution, yelp and manuals. These dependencies will need to become
something like

    yelp [!s390x !hppa !m68k !powerpc !ppc64 !sparc64],

to allow meta-gnome to continue to be installable on s390x, and ideally
also the big-endian -ports architectures.

The alternative to this would be to discuss with the release team and
make sure that they can accommodate the GNOME metapackages, and
therefore task-gnome-desktop, becoming uninstallable on s390x. In the
past this has been a problem, because britney has a concept of "faux
packages" which ensure that nothing can migrate if it would make a
debian-installer task uninstallable, but perhaps this has been resolved
now?

Yes, we should not need the alternative for this case because RHEL 10
provides a working GNOME desktop without webkitgtk.
