Sure... I guess machdep.printfataltraps prints the "trap:" line?:

trap: pid 15734.1 (sh): user PGM trap @ 0x41984d7c (SRR1=0x8d032)
pid 15734 (sh), uid 0: exited on signal 4 (core dumped)

BTW, I had said that running build.sh without -j seemed to work okay,
but I did eventually get a SIGILL later on in the process.
