build failure log
This is the configuration I do all my build testing with. Combined with "c++: error: unable to execute command: Killed" I'm guessing that you've run out of swap space (check dmesg to see why the process was killed).
You might try running /tmp/TransAutoreleasePool-692b28.sh and seeing if it runs to completion. If so, you may be able to succeed with DISABLE_MAKE_JOBS set.

Oh my word, how embarrassing, you are correct it was indeed and out of swap error, I don't know how I missed that.
I guess you can close this ticket.
All the best,
