r228152: anyone got the None cipher working with base OpenSSH?

[Freddie Cash]

Looking through the commit messages for stable/8 and stable/9 I noticed
that the HPN patches were applied to OpenSSH in the base install.  And
reading through the commit messages I see that one has to manually enable
the None cipher.  However, I cannot, for the life of me, figure out how to
do that.

The commit message for r228152 says to put "NONE_CIPHER_ENABLED=yes" into
/etc/make.conf.  But doing so still gives the following error when world is
rebuilt/reinstalled:
command-line: line 0: Bad configuration option: NoneEnabled

Putting NONE_CIPHER_ENABLED=yes into /etc/src.conf and rebuilding world
gives the same error.

And, running "make -DNONE_CIPHER_ENABLED all install" under
/usr/src/secure/usr.bin/ssh/ also gives the same error.

What am I missing?  What's the magic incantation to add the None cipher to
base ssh?
