If you don't care about Ubuntu "apport" on this system (something for
sending crash/bug reports to developers with a GUI), you could
uninstall it (otherwise it overwrites the core_pattern every time it
restarts, no matter what you write in your sysctl.conf, apparently),
and then sudo sysctl -w kernel.core_pattern=core to undo the setting
immediately (or reboot). Then hopefully the build farm would succeed
in dumping a backtrace into the log.
