WebKitGTK can no longer work on big-endian architectures as a result of an upstream move from Cairo to Skia, as announced in <https://lists.debian.org/debian-devel/2026/09/msg00139.html> and #1148038. This is one of the leaf packages that will need to be removed from s390x as a result.
Is there anything else that needs to be done for this bug? Do we need to declare a dependency on architecture-is-little-endian?
