Build fails w/ libressl-2.2.1 #153
Description
On both OS X (Xcode/Clang) and Linux (GCC) the documented build instructions for building s2n against the latest version libressl (2.2.1) do not produce a working library. Specifically, although libressl builds and installs into the local root, s2n will not compile.
On OS X, the error message is:

This seems to only affect compatibility with libressl. I was able to build s2n against openssl and all tests pass.
Thanks for working on this interesting library!
