me, on amd64 Debian Stretch.

I just reproduced it on a Linux 4.9.0-5-amd64 #1 SMP Debian 4.9.65-3+deb9u2
(2018-01-04) x86_64 GNU/Linux machine. So it doesn't seem to be the version.

Anyway, strace confirms that make is killed by SIGPIPE, so if you catch it (or
ignore it and then handle or ignore stdout/stderr write errors), it should
work.
