CentOS 8/RHEL 8 (non Stream) is EOL; unable to build CUDA pkgs

We are unable to create new CUDA packages of sac2c for the CentOS 8 distro.

Unfortunately, in an attempt to push users to CentOS 8 Stream (rolling release model), the CentOS/RHEL guys EOL'd CentOS 8 end of 2021, with a short grace-period till the repos were closed. As off now (Feb. 2022) the official CentOS 8 repos are down.

Users have the option to switch to Stream, but NVIDIA has not yet decided what they're going to do about this: https://gitlab.com/nvidia/container-images/cuda/-/issues/149. It isn't clear if they're going to provide packages for Stream, or if they move to another RHEL8 derivative distro like RockyLinux (https://rockylinux.org/).

Additionally, CentOS 9 is also out, but NVIDIA does not support it (at the moment?). Bizarrely CentOS 7 is still supported by CentOS/RHEL guys for a few more years (WTF?!?!?!?!), so building here works fine.

So the questions is, what do we do? Do we try to force a build on a unsupported distro, or do we drop it for the moment?
