Comment (by maeder):

 I still propose
 https://ghc.haskell.org/trac/ghc/attachment/ticket/8783/0001-do-not-
 confuse-configure-by-a-bash-shell.patch to be applied as is. (This would
 make my building easier for me.)

 I don't mind to change libffi/ghc.mk, too, as Edward (ezyang) suggested,
 but this is not crucial (for my builds).
