Installation fails due to missing swift-build binary

[ntpeters]

OSX: 10.11.5
Xcode: 7.3.1

When attempting to install via brew, I get the following error:

error: unable to invoke subcommand: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build (No such file or directory)

It looks like swift-build is no longer included in the installation for Xcode 7.3, per discussion here: swift-build missing in xcode 7.3?

I don't think it was ever included, only the snapshots from swift.org have it (but by now only some of them, because it was removed later in the release process). When originally developing this, Swift 2.2 implied this.

I'm going to update this to Swift 3 soon and this ambiguity should be gone again, because all variants of that should ship with the Swift Package Manager.
