Fix compile in OSX issues

[denics]

This is a first attempt to compile on OSX Sierra. At the moment it compiles, but there are still errors when linking.

This would be nice :):)

Have you been able to compile it for osx? If so how? thank you in advance

I've compiled it for 10.11+ ( http://macminer.fabulouspanda.com/commandline/sgminer/) and I used these two changes plus a minor kernel modification to skein256.cl which allowed the compiled miner to run on macOS. All I did was add parenthesis, changing this:

__constant static const int ROT256[8][4] = {
        46, 36, 19, 37,
        33, 27, 14, 42,
        17, 49, 36, 39,
        44, 9, 54, 56,
        39, 30, 34, 24,
        13, 50, 10, 17,
        25, 29, 39, 43,
        8, 35, 56, 22,
};

to this:

__constant static const int ROT256[8][4] = {
    {
        46, 36, 19, 37,
        33, 27, 14, 42,
        17, 49, 36, 39,
        44, 9, 54, 56,
        39, 30, 34, 24,
        13, 50, 10, 17,
        25, 29, 39, 43,
        8, 35, 56, 22,
    }
};

Thanks denics!

It works for me too! @fabulouspanda , maybe you can merge it?
thanks a lot!

I had a lot of trouble seemingly as I'd forked from upstream but I deleted that repo and created a pull request from a new fork with just the kernel change #9

I'm able to compile this build on macOS but executing the binary throws a lot of errors:

@aphex3k See my comment from Aug 1st which solves those issues. There are plenty of others to fix though!
