Keccak code breaks on hardware better than SSE2.

SSE2 build works fine here and on Bull. But AVX or XOP (or -native) builds fail after a wad of warnings. This also means GPU builds fail on most modern hardware since they also use -march=native.

This might be easy but I'm not sure where to start.

First couple of warnings for AVX:

KeccakF-1600-opt64_plug.c:135:6: error: #error "UseBebigokimisa cannot be used in combination with UseXOP"
     #error "UseBebigokimisa cannot be used in combination with UseXOP"
      ^

     ^

and for XOP:

As a workaround until we get it straight, we could add some #undef __SSSE3__, #undef __XOP__ and so on in some of the headers for keccak.

1fd965b seems to make it buildable on all systems. But there are tons of warnings we'd like to mute, and AVX doesn't seem to run optimal code (it's slower than SSE2).
