commit 52c037f3574eb9062b111d78a4cbeb79681d07d3

    gconv: Use 64-bit interfaces in gconv_parseconfdir (bug 29583)
    
    It's possible that inode numbers are outside the 32-bit range.
    The existing code only handles the in-libc case correctly, and
    still uses the legacy interfaces when building iconv.
    
    Suggested-by: Helge Deller <deller@gmx.de>
    (cherry picked from commit f97905f24631097af325d6a231093071c3077a5f)
