For the record EL6 repo is provided as i686 and x86_64 whereas EL7 is only provided as x86_64 at this time. This lead to an issue with multilib packages in our infra (same as EPEL). So here is the possible workaround: If there is no specific arched dependencies (either binary only or because of limited BR) The best way is to build the same package on el6, I will also tag the build on el7, so both i686 and x86_64 build from el6 will be available on el7. This is what I expect to use for libtxc_dxtn (and steam eventually).

Is steam streaming really that important ? Or in other words, can we start with just CentOS 32 bits and add EPEL 32 bits only when it comes to light ? I guess I can probably find out on my own with a custom mock conf. I'm wondering about the buildsys-build group though, as this is provided by EPEL iirc, and I'm not sure how to handle that. So far, there has only been 3 packages that I couldn't build for EL7 because of them being 32 bits only. Namely, that is steam, zsnes and unace. There are probably more, but I'll give at least these 3 and libtxc_dxtn a try, if I get a working mock setup.
