Not sure how much time it is saving us for round-trip development, but it 
feels like a waste to compile packages (and quite often) that are never used.

OBS' overall turnaround time is of bigger concern to me, it often happens that 
a bunch of packages need updating, and if we can cut that in half, everything 
will be green quicker.

Also, I have only very rarely seen differences between 64bits builds and 
32bits builds, I don't think they really matter for QA. As a sidenote, I'm 
compiling and running the whole stack for development on my 64bits laptop, so 
we'd catch build problems there already. And then there's of course the ARM 
builds, which add another arch.

Overall: IMO not worth the effort until we know that we have actual users for 
that arch, but also we might have to keep a chicken-egg situation in mind 
("build and they will come", quite literally ;)).

Cheers,
