The -j4 buildworld using a GENERIC kernel crashed at the 1.6 MB point in the logfile, which is the usual place for trouble. The debris collected is at http://www.zefox.net/~fbsd/rpi3/crashes/20180319/ Being on an RPi3, I'm still uncertain whether the problems seen are connected to the original subject. If they are not, please inform me.
