<h3>Log Message</h3>
<pre>clang-3.6: Don't rely on xcrun to find SDKs
Parse the output of `xcodebuild -sdk FOO -version` as an fallback,
fixing builds on Lion (and hopefully Snow Leopard).
The libclang_rt builds previously used a minimal stub SDK, but they
require real Xcode SDKs now.[1][2] The upstream implementation finds
them with `xcrun --sdk FOO --show-sdk-path`, but the `--show-sdk-path`
option was added in Mountain Lion.
We may have to start explicitly requiring Xcode on OS X; not sure yet.
