There is an updated pull request by kwshi against master on the void-packages repository

https://github.com/kwshi/void-packages ghcup-0.1.17.4
https://github.com/void-linux/void-packages/pull/35624

new package: ghcup-0.1.17.8
<!-- Uncomment relevant sections and delete options which are not applicable -->


#### Testing the changes
- I tested the changes in this PR: **YES**

#### New package

- This new package conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements):

  **YES**:

  1. System-wide: `ghcup` is meant to be installed system-wide, even though it
     manages per-user installations of the Haskell toolchain (essentially
     analogous to `rustup` for Rust or `opam` for OCaml)

  2. Compiled: Yep

  3. Required (by other packages): no, but it's a very useful tool for Haskell
     developers, in the same way that rustup is useful for Rust devs,
     npm/pnpm/yarn is for JS devs, etc.

<!-- Note: If the build is likely to take more than 2 hours, please [skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration)
and test at least one native build and, if supported, at least one cross build.
Ignore this section if this PR is not skipping CI.

#### Local build testing
- I built this PR locally for my native architecture, (`x86_64-glibc`)
- I couldn't test build this PR locally for other architectures because,
  apparently, we can't cross-compile with Haskell yet.
