Old packages use features and track_features to select correct clangdev * flang

[wolfv]

The flang 5 package for Windows uses the deprecated features and track_features to select the correct clangdev * flang version. Unfortunately there is no support for this usage of features in mamba and it was "deprecated" in conda.

I am wondering if we could do a repodata patch to mitigate this.

Here is the mamba issue: mamba-org/mamba#897

It's better to drop support for flang 5 and use flang 11. See conda-forge/conda-forge-pinning-feedstock#1359

Thanks for the comment. That would totally work as well. In the meantime I made this simple patch: conda-forge/conda-forge-repodata-patches-feedstock#226
