I'm now experiencing failures like the following with 'make -j5' on my 
circa-2012 desktop. They don't always happen so I assume there's a race 
somewhere. Although I don't know whether it's caused by the recent 
change, some loaddefs.el-related dependencies do seem to be missing, and 
perhaps the recent change merely exposed longstanding problems elsewhere.
