Not sure if this is necessary may help others installing #6942

Background:

With CUDA 11 the support for Kepler GPU is dropped.
Therefore if you add the flag -gencode arch=compute_30,code=sm_30 nvcc will fail

Could also add the compute_86 version in Makefile for RTX 3090 (and I guess all other RTX 30 cards)

@LeKristapino can you validate this?
As I dont have a ampere card to check.

I used https://arnon.dk/matching-sm-architectures-arch-and-gencode-for-various-nvidia-cards/ for information

@MarvinKlemp Yes, I'm running on CUDA 11.1 with RTX 3090 with

# RTX 3090, 3080, 3070
ARCH= -gencode arch=compute_86,code=[sm_86,compute_86]
