Yarn: `yarn link` should create a global symlink to the binary

Do you want to request a feature or report a bug?

What is the current behavior?

yarn link does not register the binary as a global symlink the way npm link does.

What is the expected behavior?

Running yarn link should create links to both the package main file and the bin file, the same way npm link does.

So, if my package.json contains a bin file, e.g.

{
  "bin": {
    "example": "./bin/cli.js"
  }
}

... then running yarn link should symlink bin/cli.js as example in my global bin folder, making example a global command.

Please mention your node.js, yarn and operating system version.
