Ok, the final, final swap experiment.
I created a 2G swap partition on the SDCard:
gpart show
=> 63 31116225 mmcsd0 MBR (15G)
63 2016 - free - (1.0M)
2079 102400 1 fat32lba [active] (50M)
104479 31011809 2 freebsd (15G)
=> 0 31011809 mmcsd0s2 BSD (15G)
0 25165824 1 freebsd-ufs (12G)
25165824 4194304 2 freebsd-swap (2.0G)
29360128 1651681 - free - (806M)
and, yes, it still died during make -j4 buildworld:
Jul 3 22:15:24 rpi3 kernel: pid 57011 (c++), uid 0, was killed: out of
swap space
(I forgot to start the logging script, so no stats).
Conclusion: The only way to buildworld on the RPi3B+ is to use an
external USB mechanical hard disk (my hybrid Seagate 500G 2.5" drive
required a powered USB hub). No issues on a RPi2B v1.1 with swap and
/usr on a USB memory key.
