Comment (by duncan):

 `dlopen()` cannot load .o files, only .so / .dynlib files. As I understand
 it that's the reason for the ghci linker in the first place. The system
 linker is already used for the cases it can cope with.

 Moving to building Haskell packages as shared libs would solve this
 problem for packages but not for .o files in the local build tree.
