Did you try -mv8+ ? Is there such a thing?

libssl is the thing. a long time ago i built the libssl packages for
mv8+ and put them on my website, but that was many security and other
changes ago. the point being that if you can't find any prebuilt
packages by searching these archives or with google, then it is
perfectly possible to do it yourself. i think various people have also
posted on this list what the changes are to build that lib with those
compiler switches.
This might be good for a starting place:
