The attached patch has koji build repos when you are building only for a
non-canonical arch. this would allow someone to shadowbuild fedora and build
for i686 for instance. they would get a 32 bit repo. I dont see any issues
with this unless you try to build for multiple sub-arches but that is no
different to what we have now. with this patch you will not get ppc repos
for instance if you are only building i386 but happen to have ppc packages
in the tree
