Subject: [PATCH] haskell.compiler.ghc865Binary: mark as broken when built with
 musl

The musl support for binary GHC 8.6.5 relied on ABI compat between musl
and glibc which is no longer the case: https://github.com/NixOS/nixpkgs/issues/129247

Since there is no upstream musl (alpine) bindist for GHC 8.6.5, we can
only accept that binary 8.6.5 is not possible with musl.
