It's a good thing we saw that LibreSSL works fine (and is as fast) as 
OpenSSL. For MIC it may make sense to test both (and keep instructions 
for building both but pointing out that any one of them is fine). For 
other systems (just autoconf with whatever exists) we should just detect 
what we have and use it.

If I recall right you didn't have to do anything very special with 
autoconf to use LibreSSL, right? It was seen just as if it was an 
OpenSSL installation?
