Well, I'm not in a position to give any authoritative information, but
here is what I know: With the addition of curve25519, ed25519, and
chacha20+poly1305, the developers have commented about the possibility
of building an RFC non-compliant OpenSSH without OpenSSL.

If you search through the mailing list archive, I believe you chould see
some references to this. There are also commtnes in the CVS commits
regarding this. And, I believe Damien mentioned about this in his
interview on bsdnow.tv.

In one of the CVS commits, I noticed that there is support for falling
back on libc for digest support when building without OpenSSL, but I
don't recall if this is both MD5 and SHA1 or not.
