Thank you for raising this. However, cpuinfo is a (often unconditional)
B-D of some other packages, e.g. pytorch and onnxruntime.

In other words, they require cpuinfo to build, but does not actually
use it on all platforms.

"dak rm -BRn --architecture=s390x,ppc64el cpuinfo” shows:

 # Broken Build-Depends:
 onnxruntime: libcpuinfo-dev (0.0~git20240830.fa1c679 >=)
 pthreadpool: libcpuinfo-dev
 pytorch: libcpuinfo-dev (0.0~git20230113.6481e8b~ >=)
 pytorch-cuda/contrib: libcpuinfo-dev (0.0~git20230113.6481e8b~ >=)
 ruy: libcpuinfo-dev (0.0~git20220617.082deff-2 >=)
 xnnpack: libcpuinfo-dev (0.0~git20231104.d6860c4~ >=)

Removal of cpuinfo binary packages on these platforms would typically
require patching of all these packages. I would not recommend doing
so especially when we are facing the trixie hard freeze very soon.

Thanks,
