Describe the bug

I am trying to ramp back up on riscv64-linux stuff. I have a minimal builder config that cross-compiles. I'm trying to get the "full" interactive config ready to natively build, but it doesn't even evaluate.

It blows up on GHC. If I were guessing, it seems like some versions of GHC are pulled as binary releases, probably to bootstrap a GHC-from-source build.

However, it seems that GHC does not publish binary releases of GHC.

I'm not in the Haskell scene, so I don't know how to proceed:

1. Ask GHC to publish riscv64 releases? Not sure if they're ready yet, etc
2. Use an unsupported binary release from ... someone else? Maybe this couldn't/shouldn't be merged, but could live in one of the various riscv64 branches that various folks maintain.
