I'm not sure I understand the necessity of this. What matters for 
reproducibility is that rpms install the same files; why is it important 
that the rpm file itself has exactly same build time and is otherwise 
identical bit by bit?

A technicality: do not patch mnacros.in, set the macro directly from 
package_rpm.bbclass.
