I think that most distros don't link against OpenSSL because they can't
take advantage of the system library exception. I don't think that's
going to change.
If we want to consider performance-related concerns, I think the easier
solution is using Nettle, which is LGPL 2.1. Considering that the
current opinions for a new hash function are moving in the direction of
SHA-3, which Nettle has, but OpenSSL does not, I think that might be a
better decision overall. It was certainly the implementation I would
use if I were to implement it.
