make build-all fails on ppc64le

[seth-priya]

The build is failing with the following error
if [ -e ./base-notebook/Dockerfile.ppc64le.patch ]; then
if [ -e ./base-notebook/Dockerfile.orig ]; then
cp -f ./base-notebook/Dockerfile.orig ./base-notebook/Dockerfile;
else
cp -f ./base-notebook/Dockerfile ./base-notebook/Dockerfile.orig;
fi;
patch -f ./base-notebook/Dockerfile ./base-notebook/Dockerfile.ppc64le.patch;
fi

make: *** [arch_patch/base-notebook] Error 1

This is because the patch file base-notebook/Dockerfile.ppc64le.patch is out of date and needs to be updated.
