jailbreak = true seems to be failing on a conditional flag

[locallycompact]

Here's a flag in monoidal-containers that jailbreak seems to be struggling with:

https://github.com/bgamari/monoidal-containers/blob/5968c2448ae46855c2736dd9b97a5493886d1ce4/monoidal-containers.cabal#L66-L72

https://gitlab.horizon-haskell.net/package-sets/horizon-platform/-/jobs/63910

This is unfortunately the behavior of jailbreak-cabal: #7

There are a bunch of closed issues on this issue tracker and on the nixpkgs issue tracker complaining about this. But it is a tough problem because of how complicated cabal is.

Documented behavior. Would need haskell/cabal#7445 instead (or us reimplementing this here somehow).

Hi. Ran into this for another package today. Did we find a solution or an acceptable workaround for this yet?

Normal workarounds are patching or sed'ing the cabal file.

I am working on haskell/cabal#7445, but upstream wants to do it right. So it's taking a while.
