ghc, ghc-bin: add aarch64-musl support
GHC uses llvm (specifically `opt` and `llc` executables) to build on aarch64, so that was added as a dependency.

All packages that dependent on ghc were built and are available at a [repo I made with signed *.xbps files](https://ftrv.se/_/void/ghc-aarch64-musl) along with the [ghc bindist distfile](https://ftrv.se/_/void/ghc-aarch64-musl/ghc-8.10.7-aarch64-void-linux-musl.tar.xz) required by ghc-bin, which this change assumes is eventually uploaded to `alpha.de.repo.voidlinux.org`. I tested most of the packages, they all work as expected.

I can share the files in some other way if that's preferable.

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

#### Local build testing
- I built this PR locally for my native architecture, (aarch64-musl)
