Help with build ordering issue

[Sylvain Henry]

Hi,

@Bodigrim is working on a patch (https://phabricator.haskell.org/D4212) 
to fix #14170.

The build fails because of interface file errors: "bad interface file" 
for GHC.Natural and "failed to load interface" for GHC.Types.

I suspect it is a wired-in module build ordering issue but I haven't 
been able to help fixing it. If anyone with more insights could help it 
would be much appreciated!

Thanks,
Sylvain
