Comment (by simonmar):

 I think this is probably something in the RTS linker.  I'm debugging it on
 Edward's machine but I'm stuck on a permission problem for now.

 @erikd My guess is that if you add `DYNAMIC_GHC_PROGRAMS=NO` to your
 build.mk with `perf-llvm`, then GHCi will be completely broken.  Perhaps
 something in LLVM is tickling a missing or broken case in the linker.
