Haskell breakages on 32bit

[Chris Warburton]

GHC bug https://gitlab.haskell.org/ghc/ghc/-/issues/17950

This affects the locking used by cabal-install, e.g.
https://github.com/haskell/cabal/issues/6602

It seems to come from the 'lukko' library:
https://github.com/phadej/lukko/issues/15

This certainly affects anything using haskell.nix

If the workaround of compiling cabal with 'lukko -ofd-locking' can be easily
implemented, e.g. via some minimal override, then it might be worth doing. It
would trigger a lot of rebuilding though.
