haskell.compiler.ghcHEAD: 9.7.20221224 -> 9.7.20230217

- Christmas is over!

- Upstream has changed the name of the target triplet used for the JS
  backend from js-unknown-ghcjs to javascript-unknown-ghcjs, since Cabal
  calls the architecture "javascript":
  6636b67023

  Since the triplet is made up anyways, i.e. autoconf does not support
  it and Rust uses different triplets for its emscripten backends, we'll
  just change it as well.

- Upstream fixed the problem with ar(1) being invoked incorrectly by stage0:

 - Calling `makeSetupHook` without passing a `name` argument is deprecated.
 
+- `lib.systems.examples.ghcjs` and consequently `pkgsCross.ghcjs` now use the target triplet `javascript-unknown-ghcjs` instead of `js-unknown-ghcjs`. This has been done to match an [upstream decision](https://gitlab.haskell.org/ghc/ghc/-/commit/6636b670233522f01d002c9b97827d00289dbf5c) to follow Cabal's platform naming more closely. Nixpkgs will also reject `js` as an architecture name.
+
 - The `cosmoc` package has been removed. The upstream scripts in `cosmocc` should be used instead.
 
 - Qt 5.12 and 5.14 have been removed, as the corresponding branches have been EOL upstream for a long time. This affected under 10 packages in nixpkgs, largely unmaintained upstream as well, however, out-of-tree package expressions may need to be updated manually.
