Motivation for this change

Mxnet doesn't build with cudaSupport:

$ nix run "(with import <nixpkgs> { config = { allowUnfree=true; cudaSupport=true; cudnnSupport=true; }; };
python3.withPackages (ps: [ ps.mxnet ]))"

builder for '/nix/store/f5zwrjv4ad0y8p2qk6472d4ryx7nvzm8-mxnet-1.2.1.drv' failed with exit code 1; last 10 log lines:
