Build Deep Speech from source, macOS 10.12.6

I have just tried to build Deep Speech from source.

pwd shows that I am in the native_client directory. DeepSpeech and tensorflow are in adjacent directories.

This appears to instruct the build system to build the binaries:

bazel build -c opt --copt=-O3 //tensorflow:libtensorflow_cc.so //tensorflow:libtensorflow_framework.so //native_client:deepspeech //native_client:deepspeech_utils //native_client:libctc_decoder_with_kenlm.so //native_client:generate_trie

Running the above results in:

ERROR: The 'build' command is only supported from within a workspace.

To get further, I have tried to touch ../WORKSPACE and touch WORKSPACE. This gives me new errors.

Our documentation in native_client/README instructs to do the bazel build call from within the TensorFlow checkout :).

I misread that then. I will try and make the wording more explicit.
