Tor running with LibreSSL 2.5.5 (latest stable):

[notice] Tor (git-c33db290a9d8d0f9) running on Linux with Libevent 2.1.8-stable, OpenSSL LibreSSL 2.5.5 and Zlib 1.2.11.
[notice] 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.

LibreSSL doesn't have this configure option and I don't think that there are any problems with ECDH.

Maybe its time to remove the warning?
