Purging chroot-autobuild/build/buildd/regina-normal-4.6
This isn't arm-specific, it just happened to only affect arm and powerpc because of the timing of the builds wrt the multiarch library transition. So regina-normal almost certainly also ftbfs on i386 and amd64 now also, and needs fixed for finding X libs.
