wrong hoogle database for multi-library packages

[Lysxia]

For example https://hackage.haskell.org/package/vector-0.13.2.0/docs/vector.txt currently shows data for the vector:benchmarks-O2 sublibrary instead of the main vector library. I would hazard a guess that Hackage is generating two hoogle databases with the same file name, so one overwrites the other.

I would hazard a guess that Hackage is generating two hoogle databases with the same file name,

haddock, as told by cabal-install.

Because doc builder still uses v1-build (#1393, the issue existed really from 2019: e.g. #821), I don't expect this to be fixed any time soon. I doubt v1-haddock will be fixed, and even if v2-haddock already works (which it might not), it has to be used first.

v2-haddock seems to suffer from the same issue: haskell/cabal#9586 (comment)
