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

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

@isuruf This one is ready for review. It is needed to build all of the CDTs. It should not cause any issues for the current compilers once we merge the binutils fix.

[beckermr]

OK. We should be good to merge this one too @isuruf! You approve?
