Anyways - this is an out of memory problem.
dmesg will show you why the process was killed.
You have to add more swap space.
Unfortunately compilers get more and more CPU and memory hungry.
These days I use memory sticks capable of high random load as temporarys
swap space or NFS space - later mostly for obj and src, not as swap so much.
For me SanDisk Extreme Go 3.1 and Ultra USB 3.0 worked great.
That said, I havn't build FreeBSD12 on any ARM myself yet and this is
only a general experience.
