[Tor-BSD] Recognizing Randomness Exhaustion

[Libertas]

I also completely forgot to mention the below warning, which Tor
0.2.5.10 (the current release) gives when run on OpenBSD 5.6-stable amd64:

> We were built to run on a 64-bit CPU, with OpenSSL 1.0.1 or later,
> but with a version of OpenSSL that apparently lacks accelerated
> support for the NIST P-224 and P-256 groups. Building openssl with
> such support (using the enable-ec_nistp_64_gcc_128 option when
> configuring it) would make ECDH much faster.

Were the mentioned SSL features removed from LibreSSL, or have they not
yet been introduced? Could this be the culprit?
