Okay, so here are two patches:
fedpkg-1.10-use-nil-to-unset-distunset.patch (this one uses %nil instead
of 0 in my previous fix)
fedpkg-1.10-unset-runtime-disttag.patch (this patch detects the runtime
environment and unsets the version specific tag (e.g. %{fc17} or
%{el6}), except in the case where the runtime env matches the build
target exactly)
Jesse, please review and apply these upstream and make a new update.
