Due to bugreport
 http://bugs.gentoo.org/165444
 https://bugzilla.mindrot.org/show_bug.cgi?id=1008
a patch was introduced net-misc/openssh/files/openssh-7.2_p1-GSSAPI-dns.patch
+   const char *gss_host;
+
+   if (options.gss_trust_dns)
+       gss_host = get_canonical_hostname(1);
+   else
+       gss_host = authctxt->host;

Unfortunately the function get_canonical_hostname was removed, comment in Changelog:

    auth_get_canonical_hostname in portable code.
    
    "refactor canohost.c" replaced get_canonical_hostname, this makes the
    same change to some portable-specific code.

commit 95767262caa6692eff1e1565be1f5cb297949a89
Author: djm@openbsd.org <djm@openbsd.org>

    upstream commit
    
    refactor canohost.c: move functions that cache results closer
     to the places that use them (authn and session code). After this, no state is
     cached in canohost.c
    
    feedback and ok markus@

So with the patch this breaks gssapi as mentioned in the mindrot.org burgreport.
