Your C library has a setlogin function so sshd uses it.  It doesn't work
and ssh reports this as an error because, well, it's an error.

Remove HAVE_SETLOGIN from config.h or complain to whoever wrote the C
library.

The kernel version is probably irrelevant, it's the version of the C
library that matters.

On platforms without their own setlogin() the replacement in
openbsd-compat/bsd-misc.c (an empty stub) is used, since libopenbsd-compat
is ahead of libc in the link order.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
