GHCI fails to run for ghc@8.6.5 |

To reproduce, just guix environment --ad-hoc ghc -- ghci. ghc@8.4.3
works. Seems like this may be related to some Prelude changes upstream
(https://gitlab.haskell.org/ghc/ghc/issues/16563), but I'm not
familiar enough with GHC internals to really tell what's going on.
Interestingly, when I try to run plain old GHC on some source files
with 8.6.5 I get another seemingly unrelated error:
Bad interface file:
/gnu/store/8v1sn5ns7r5n02aip0b0ypyyzb2y1i1a-ghc-8.4.3/lib/ghc-8.4.3/base-4.11.1.0/Prelude.hi
mismatched interface file versions (wanted "8065", got "8043")
|
1 | import Test.Hspec (Spec, it, shouldBe)
| ^
Again, I'm afraid I'm not entirely familiar with GHC internals and the
function of interfaces files. Nevertheless, it seems not all is well
in Guix-Haskell-land.

Thanks for checking so quickly. :)
