FFI library error building GHC

[member MP2E]

Symlinking lib64 to lib didn't seem to work, I think the directory is
getting cleared before build. But if I copy the contents of lib64 to lib
after the build fails and then type make again, ghc compiles!

Thanks for the workaround, hopefully a real fix will be found soon enough :)
