    Enable Large File Support for Disks
    
    Dealing with large files (2 GiB+) on 32-bit systems requires
    special compiler flags to enable support. Currently, any
    attempt to mount or create a large image file in Disks
    results in an error.
    
    The fix is to add the proper compiler flags to enable LFS.
