dlopen will load pretty much any elf object file. There is little
special about shared libraries in Linux. The position-independent code
only localizes the changes that need to be made on link, so that more
pages can be shared. Libraries work just fine without it.
But, as someone pointed out, some of these files contain haskell code,
and I'll have to look more into whether or not that will work.
