For information, I also opened an issue with docker because it might
be an ubuntu:16.04/seccomp issue

I'll keep you posted, but it's interesting that emacs needs
`personality` syscalls in order to build. I'm curious about why there
is this somewhat intermediate "temacs" binary that seems to have the
ability to dump itself into the final binary.
