Actually ... (3) i[3,4,5,6]86 things are potentially required in the
x86_64 tree for building x86_64 RPMS: glibc.i386, glibc.i686,
glibc-devel.i386.  That exclude line does allow for all those to get
called in when required, but blocks all other i386 arch content.  It
might not be "required" for EPEL (if you don't build any packages that
need both 32 and 64 bit parts), but it is certainly required for Fedora
and CentOS/RHEL base OSes if building in mock. 

Also, if koji uses the same "Stage" repo functionality as plague (I am
not sure how koji does its "generated" repos {or even if it does self
generated repos}), you might also need to exclude x86_64 rpms in the
i386 mock configs.  (In plague the Staged feature {at least in our
setup) does one set of repo metadata that contains all i386, x86_64, and
all other arches.  This means that when solving deps, all arches can be
looked at and potentially called out of arch)

Again, this may or may not also be how koji does staged repos ... just
food for thought.
