Comment:

 >  can we have a fix for this before the final 8.0.1 comes out

 Seems like an suitable task for a newcomer.

 * The code is in `compiler/main/DynFlags.hs`.

 * Don't forget to update the documentation in the `docs/users_guide` and
 `utils/mkUserGuidePart` directory.

 * Submit your patch to [wiki:Phabricator].
