Subject: [PATCH] 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)
