Subject: [PATCH] Revert "Merge pull request #17145 from
 kalhauge/haskell_darwin_dyld"

This fix doesn't actually fix the cabal bug (see #16357), but it does
cause other bugs (see #20476)

Fixes #20476

This reverts commit b89fa5fd5cc3e7d27fb87bc792fe0d6553aec28d, reversing
changes made to e4b146b0417762c461c7f90f587dc82e8524f796.
