[swift-server-dev] import Foundation => could not build Objective-C module 'CoreFoundation'

Has anyone been able to `import Foundation` using a development snapshot on Ubuntu 14.04? I'm getting errors that make it seem like my environment isn't setup correctly, but the same environment works fine for the 3.0.2 release.

```

Welcome to Swift version 3.1-dev (LLVM 7e421db87c, Clang 8df9d5d9f9, Swift 6f08335ce0). Type :help for assistance.
  1> import Foundation
  
error: /usr/include/x86_64-linux-gnu/sys/types.h:146:10: error: 'stddef.h' file not found
error: /usr/lib/swift/CoreFoundation/CoreFoundation.h:25:10: error: could not build module 'SwiftGlibc'
error: /usr/include/x86_64-linux-gnu/sys/cdefs.h:23:11: error: could not build module 'SwiftGlibc'
error: could not build Objective-C module 'CoreFoundation'
```

I've tried manually providing some include paths to the swift command, which did remove the SwiftGlibc error, but nothing else seems to be working out for me :-(

```

error: could not build Objective-C module 'CoreFoundation'
```

Since the 3.0.2 release version can import Foundation no problem, I'm wondering if there's something I'm missing when setting up a new development snapshot?
