+
+The native version of ldconfig was using native definition of LD_SO (i.e.
+ld-linux-x86-64.so.2 ) which is not correct for doing the cross ldconfig.
+This was causing libc.so on the target marked as ELF lib rather than
+FLAG_ELF_LIBC6 in the ld.so.cache.

+Subject: [PATCH] Add 64-bit flag for ELF64 entries.
+
+ldconfig-native was grepped from an old version of glibc, and its output
+lacks neccessary 64bit flag in entries.
+Due to this defect, ctypes.util.find_library() python function fails to
+detect any library due to the old file format that ldconfig-native
+creates. This fix sets architecture-dependent 64bit flags for 64-bit ELF.
