commit f50a6c843a5b5186c0aa73747de033e08ef8246d
Author: Florian Weimer <fweimer@redhat.com>

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.
