A similar issue was discussed on nvidia's github (https://github.com/NVIDIA/open-gpu-kernel-modules/issues/405), however it turned out to be a different problem. The fix proposed during the discussion fixes this issue for me. It does not seem like it was further considered for merging. I adjusted the proposed to Gentoo's folder structure and attached it below. Not sure if it should be fixed on Nvidia's side or (also) here. It does not seem like the Makefile is considering LDFLAGS in general. In the ebuild I can see that adding the -m flag has been done for compiling the tools.

But not the first of this issue, just have to copy what previously did for nvidia-settings until nvidia comes up with their own solution.

Not a perfect fix given profiles don't define LDFLAGS_arm64, but that's not a high priority and can wait for nvidia's fix. Note that modules are still generally fragile and untested with llvm toolchain.
