Description

Fresh kudu build on my mac (OS X version 10.11.5) fails to compile during thirdparty/build-if-necessary.sh:

After installing Xcode, the builds succeeded.

In discussion with mpercy, we thought it would be better to explicitly update the docs about OS X dependency on Xcode along with the xcode cmdline utilities. Mike mentioned something about not being able to recollect any extra dependency other than xcode-select utilities. However, as mentioned above, I had to install Xcode as well for a successfull build on latest OS X.
