a96856c266
Backport a patch (which probably addresses a completely unrelated issue with hadrian and system libffi for GHC >= 9.2.3) that stops Cabal from handling libffi includes in libraries/ghci. This allows for cc-wrapper to freely pick the correct libffi which is important when cross compiling GHC as we need to correctly pick between build and host/target libffi each time. This fixes the build of pkgsCross.riscv64.haskell.compiler.ghc8107. Tested - haskell.packages.ghc8107.cabal2nix (x86_64-linux, aarch64-linux) - pkgsCross.riscv64.haskell.compiler.ghc8107 (x86_64-linux) Could not test darwin because rcodesign is broken at the moment (?).
