Set -Wno-prepositive-qualified-module in Paths_*.hs

[matthewbauer]

This is based on / similar to #7219

We used import qualified M in Paths_*.hs, which might be disallowed in
GHC 8.10 when -Wprepositive-qualified-module is set.

Maybe it would be easier to use https://downloads.haskell.org/ghc/latest/docs/html/users_guide/using-warnings.html?highlight=w#ghc-flag--w

{-# OPTIONS_GHC -w #-}

[Mikolaj]

I guess it would be easier and more future proof, though a bit less safe. @matthewbauer, what do you think?

[matthewbauer]

Yeah, that's fine with me - I've updated with this change. I suppose there could be warnings in Paths_*.hs that we do want to know about, but then again it's pretty small and I don't think it will hurt to ignore those warnings.

[Mikolaj]

I didn't quite pass the checks. Warnings turned into errors, probably.

[Mikolaj]

@matthewbauer: ping! :)

[matthewbauer]

ok! updated with what I think fixes the issue...

[Mikolaj]

@matthewbauer: thank you, the checks passed. @phadej: does it look good to you?

[Mikolaj]

No objections from @phadej, but he is busy, so I've added myself to reviewers instead. LGMT. Merging.

[Mikolaj]

@emilypi: what's our etiquette, do I hit 'merge' now or ask the esteemed contributor to do so or seek yet another approval?

[emilypi]

@Mikolaj we generally want 2 approvals before merging. I'll have a review in today.

[Mikolaj]

Thank you @matthewbauer, @phadej and @emilypi!
