xgboost 2.1.1 is not supported on this platform

[xhochy]

I'm seeing this issue across many platforms locally and in CI of other feedstocks, e.g. for cuda 11.8 builds:

+ pip check
xgboost 2.1.1 requires nvidia-nccl-cu12, which is not installed.
xgboost 2.1.1 is not supported on this platform

For osx-*, it's only ( e.g.xgboost-2.1.1-cpu_pyhb8f9a19_1):

+ pip check
xgboost 2.1.1 is not supported on this platform

@hcho3 could you please take a look?

So the CUDA 11.8 & 12 packages appear to be fixed

However the CPU-only package is still showing an issue

$ pip check 
xgboost 2.1.1 is not supported on this platform

Am not sure why that is

Note: Did try installing nccl in the CPU-only case, but the error persists. So this doesn't appear to be as simple as checking for NCCL

I looked at the nannyml case and am a bit confused. The nannyml job has py-xgboost=2.1.1-cpu_pyhf829fab_3 where as the CI job here for build no 3 and CPU actually lists that it builds py-xgboost=2.1.1-cpu_pyhc68e8b7_3. https://anaconda.org/conda-forge/py-xgboost/files lists even more packages.

Looking at the OSX logs, we can see that the wheel are not actually noarch: xgboost-2.1.1-py3-none-macosx_12_0_x86_64.whl So we probably are mixing platforms here and the wheel tags don't carry the right information.

Should be fixed by #194
