From adbf0b1fdf897076e5e3dec2443c8927f315c2e6 Mon Sep 17 00:00:00 2001 From: Shan Hai Date: Fri, 24 Oct 2014 14:05:36 +0800 Subject: ldconfig-native: fix a endian-ness bug Some header fields of ELF were read with wrong size on 64bit big-endian machine, fix it by reading the fields with read64 instead of read32.
