Comment (by bgamari):

 One interesting observation is that there are two modules named `Base.o`
 that get placed in the archive file,
 {{{
 $ ar t dist-install/build/libHSbase-4.10.0.0.a | grep Base
 Base.o
 Base.o
 }}}
 One of these is `GHC.Base` and the other is `Control.Exception.Base`.
 Given that `ar --print-armap` reports `base_GHCziBase_return_info` as
 defined I wonder whether the RTS linker fails to find the symbol due to
 this repeated object name.
