 In #7806, Kazu reported that on OS X:

 After "make install", the installed GHC refers to libffi in the build
 directory.
 {{{
 % otool -L ghc | grep libffi

     /Users/kazu/work/ghc/libffi/build/inst/lib/libffi.6.dylib
 (compatibility version 7.0.0, current version 7.0.0)
 }}}
 So, after I did "make maintainer-clean", the installed GHC could not find
 a libffi.
