CUDA 9.0 transition

[Andreas Beckmann]

Hi,

CUDA 9.0 finally reached experimental. Did someone get around testing
it, yet?

I'd like to start the transition soon. There are only two rdepends left
in testing (and going to be autorm'ed in 5 days) - both pycuda and
hwloc-contrib seem to be (manually) binNMUable.
I didn't test the other rdepends that are in sid only. But they will
need sourceful uploads anyway for switching the compiler (to gcc-6/g++-6
- not the default, but the best we can get and still better than clang-3.x).
