   Researching the build logs from the first crash... I see that mkldnn is set to 0 in some of the earlier build routines, but when making the docs, mkldnn files are being built by mshadow:
   ```
   + make docs SPHINXOPTS=-W
   /work/mxnet /work/mxnet
   make -C docs html
   make[1]: Entering directory '/work/mxnet/docs'
   export BUILD_VER=
   Env var set for BUILD_VER: 
   sphinx-build -b html -d _build/doctrees  -W . _build/html
   Running Sphinx v1.5.6
   making output directory...

   ```
   
   Then down further I see more...
   ```

   ```
   So would this help reveal why docs is experiencing the same kind of crashing?
