Make all of the SocksCoreExample* optional or move to example folders

[proyb6]

Will need to simplify the dependencies when compiling Vapor and move those "example" to a separate folder will helps to reduce compiling time if that is not need.

In macOS 10.11.6 beta Error on Xcode 8 beta with Toolchain on Swift June 20.

Hi @proyb6, is this two separate issues? To me it looks like a compilation issue (I'll take a look into it), and also a request to move the example binaries. Could you please create a separate issue for each so that we can more easily focus the conversation? Thanks 😊

What changed to get past the !tapi-tbd-v2 error?

I updated Socks, and it went away, but later on in my project I'm getting it in final link What an annoying error! There's practically nothing google knows about it, other than this thread.
