Daniël de Kok 590ce7d1ae mxnet: fix library dependencies.
- mxnet now builds the open source MKL DNN library. However, this
  was not included with the build.
- mxnet builds its own OpenMP library, even when OpenMP is provided
  by the system. This leads to problems, so remove the included
  OpenMP implementation:
