 When using the FFI's capi calling convention to get access to #defined
 constants ghci produces the following error:

 ByteCodeLink: can't find label
 During interactive linking, GHCi couldn't find the following symbol:
     ghc_wrapper_<mangled string>_<symbol name>

 Compiling via the commandline works just fine. Attached is a minimal test
 case. "ghc minimal.hs" produces a working binary, but "ghci minimal.hs"
 produces the above error.
