The build is using `/Library/Developer/CommandLineTools/usr/bin/make`,
which suggests that you have the Command Line Tools directory selected
as your active developer directory.

Firstly, we don't support this configuration in general.

Secondly, the most recent compiler-rt requires an OS X SDK on Darwin,
which the CTL package does not provide. You'll have to switch your
active developer directory to `/Applications/Xcode.app` or wherever you
put your Xcode.

We should start requiring Xcode for clang-3.6, or maybe cutting out
compiler-rt if the OS X SDK is absent. And the build should not be
trying to install a library that it didn't build, but that's an upstream
issue.
