Looking for Ryzen owners to test SHA acceleration.

Ryzen CPUs have HW accelerated SHA, something Intel's mainstream CPUs won't have until Cannonlake.

Requirements:
  Ryzen CPU
  Linux
  Compiler version with support for sha
  Openssl development package with support for sha
  Cpuminer-opt source code with support for sha

I can provide the last one. GCC is supposed to have support for -msha starting in v 5, and Openssl added support in 2014
so both should be available in Ubuntu 16.04.

The following algos use sha256 and should benefit from HW acceleration: sha256t, lbry, skein, myr-groestl, m7m.
