Comment (by bgamari):

 It would be likely be helpful if someone affected by the issue could post
 the simplified Core and STG of `UI.hs` from their stage 2 build. Running
 the following should do the trick,
 {{{
 $ touch ghc/GHCi/UI.hs
 $ make GhcStage2HcOpts='-ddump-to-file -ddump-simpl -ddump-stg'
 }}}

 You should then find `UI.dump-{simpl,stg}` files in `ghc/GHCi`. Be sure to
 also take note of which symbols appear in the "referenced from" list in
 the linker error.
