`mincore()` is not a reliable way to determine whether a region is empty. This could result in an already-in-use region being mapped with `MAP_FIXED`, and Wine conflicting with its original owner (i.e. dyld).
With the `mincore()` check removed, a special case was added to allow zero-fill sections to be mapped.
