Fixed a bug: If all output data was discarded (by using file = "" in the

linker config), CheckExports was never called, which in turn meant that
the list of all exports was never built. This caused a crash later when
the linker tried to generate a map file. The solution is to separate the
creation of the exports list and the check for unresolved imports.
