wl-kmod/devel not building on i686 (possibly affecting all kmods?)

I've noticed for a little while and mentioned it on IRC that the wl-kmod/devel package is not getting built on i686. It doesn't fail, it just doesn't build at all for i686 - like it doesn't even get queued. See job #3483 for example. All fine on non-rawhide. Seems to be affecting some other rawhide kmods too such as job #3478 which is fglrx-kmod. Anyone know what'd happening with it or if there is something I need to fix in the spec to make it build? Or is this just a buildsys problem? Ta C
