Subject: [PATCH] Patch from Greg Burd: Improve portability of the
 build-apidoc.sh script by replacing readlink

Review: https://reviews.apache.org/r/6733/

Testing: Applied patch, and ran 'ant clean-all build-apidocs'
on both OSX and Ubuntu 12. Initial testing confirmed the issue
that Greg discovered on OSX.  After the patch, the docs built
correctly.
