I doubt there is a difference, as both are OpenSSL forks.  And 
such a support will seriously complicate the code with no obvious 
benefits.  Though I've never tested nor looked into the current 
sources of these libraries for this particular aspect.

Either way, if it is implemented by the library, it's highly 
unlikely that any changes in nginx will be needed.  It already does 
all it can do.
