Synchronized external modules as upstream

Now CUDA v7.5 is required, along with new cudnn: cudnn-7.5-linux-ppc64le-v5.0-ga.tgz.

NOTE: GitHub's packaging doesn't include submodules for this tag.

Please proceed as following to get all the file appropriately:

git clone https://github.com/PPC64/torch-distro.git --recursive
cd torch-distro
git checkout v1.1

Or else ./install.sh will not work

GPU working on ppc64

Tested this torch version on Ubuntu 14.04 with CUDA v7.0 (cuda-repo-ubuntu1404-7-5-local_7.5-18_ppc64el.deb) and CUDNN v4.0 (cudnn-7.0-linux-ppc64le-v4.0-prod.tgz) and there was GPU activity (nvidia-smi output).

I had to comment out this test on the test.sh suite due to this bug and then I saw them running.
