Update to GHC 9.8.2 (nightly-2024-03-26)

[tbidne]

Thought I'd open this to get the ball rolling, though I understand if we want to wait until more packages are added.

General Notes

Dropped packages

With this PR the package count drops by about 200:

-- master
λ. grep == clc-stackage.cabal | wc -l
2876

-- this
λ. grep == clc-stackage.cabal | wc -l
2643

In particular, quite a few amazonka packages have dropped out, so perhaps we want to wait for that to be fixed before merging.

New system dependencies

There are a couple new system dependencies:

• openssl (required by core-telemetry, cql-io)
• primecount (required by primecount)

Excluded packages

Other than exes, of the new packages that appeared in this snapshot, I excluded:

• cuda: Requires proprietary CUDA deps.
• stack: Requires custom GHC to be on the PATH as it is used in TH. If this isn't considered too onerous I can add it.

Nix

@googleson78

There isn't too much that is new here, other than documenting why some system libs are needed.

The main change is having nixpkgs.follows = "ghc_nix/nixpkgs". I did this since we need the custom GHC to be built with the same glibc as the system libs. Because ghc.nix is a (the most?) popular way to build GHC with nix, it seems useful to make this relationship explicit. Case in point, I made this change after running into errors using a recent version of nixos-unstable here, as my ghc.nix built compiler was on an earlier glibc.

Note that ghc.nix's current nixpkgs is fairly old (September 2023).

Thanks @tbidne! I think re-adding stack is worth it. And let's wait a bit longer for amazonka.

[Bodigrim]

@tbidne could you please regenerate it with the latest nightly? I'd like to go ahead with it.

[tbidne]

Can do. Note the amazonka issue is still unresolved, though I suppose it probably makes more sense to update to GHC 9.8 now and update again later as necessary.

[Bodigrim]

Yeah, let's skip amazonka for now.

[tbidne]

@Bodigrim I updated the package set. I'm about 30% of the way through building it, and it looks like we took on a couple more system dependencies (fftw and expat so far). If you don't mind waiting a day or so, I should have enough cpu cycles by then to get through everything.

[Bodigrim]

Thanks for working on this, much appreciated!

[tbidne]

@Bodigrim Just finished. Everything built except for 3 packages: grisette, hw-json-simd, and sbv. I am confident these are nix problems (documented here), so this can be merged AFAICT.

[Bodigrim]

Thanks a ton!

[tbidne]

Thanks for merging!
