Not all i686 systems have support for SSE. I don't think we should
apply the upstream suggested workaround, which effectively amounts to
dropping support for older systems. If we want to add a requirement for
SSE for i686 systems in Guix, that should be a separate discussion, and
not rushed in as part of a security update.
I will adapt my patch to the new version.
