Even when there are deployments, they do not typically use QEMU, as QEMU is less important for Xen on ARM compared to x86. The QEMU project only test to cross-build Xen on Aarch64 hosts (see 84eda110792 ("gitlab-ci: Add Xen cross-build jobs"). Since 32-bit host aren't tested, simply remove the support there.
