Use noarch: python for Python packages

[conda-forge-admin]

As the XGBoost Python packages are pure Python (using ctypes to interact with the libxgboost library), there is no need to build these for every Python version and architecture. So simply mark these as noarch: python to get the minimum needed builds and move on.

Hi! This is the friendly automated conda-forge-webservice.

I've started rerendering the recipe as instructed in #127.

If I find any needed changes to the recipe, I'll push them to this PR shortly. Thank you for waiting!

Here's a checklist to do before merging.

• Bump the build number if needed.

Fixes #127

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe:

• It looks like the 'libxgboost' output doesn't have any tests.
• It looks like the '_py-xgboost-mutex' output doesn't have any tests.
• It looks like the 'py-xgboost-cpu' output doesn't have any tests.
• It looks like the 'py-xgboost-gpu' output doesn't have any tests.
• It looks like the 'xgboost' output doesn't have any tests.
• It looks like the '_r-xgboost-mutex' output doesn't have any tests.
• It looks like the 'r-xgboost-cpu' output doesn't have any tests.
• It looks like the 'r-xgboost-gpu' output doesn't have any tests.

@conda-forge-admin, please re-render

@hcho3 , could you please review? 🙂

We could consider dropping some of the Python mutex packages at this point since really only selecting libxgboost matters for that case. Maybe even revive PR ( #35 ). Though maybe this is easier to do in conjunction with 2.0.0?

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but it appears we have a merge conflict.
Please try to merge or rebase with the base branch to resolve this conflict.

Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.
