These two fields allow to specify a different default assignee for ticket opened against
this package in bugzilla. Note: The EPEL field is
always displayed for packages in the 'rpms' namespace regardless of whether it
is used in bugzilla or not.
Update to 4.4.0, re-enable tests on ppc64le.
I'm not sure I actually needed to build 4.3.1 first, but I guess it
didn't hurt anything.
