We don't currently have a good procedure for that. Normally one has to actually run the mkall.sh script on a system of the type you are trying to update. Using QEMU could work in principle. For ARM GNU/Linux zsysnum is updating by running curl (see mkall.sh) which is probably why that failed to update.
