This answer is a bit late to the party, but you can also compile static openssh binaries (ssh sshd ssh-keygen etc) for android using the buildroot project. Or dropbear if you prefer.
https://buildroot.uclibc.org/downloads/manual/manual.html
I have done this on my linux box, for openssh and many other programs. This requires a rooted device.
My device was arm based - you would have to check if your device is supported by buildroot if it is not arm.
