Sorry I was on the wrong tree and was one patch behind. Please see the
revised patch.
Best,

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.
Since the host's elf.h may not have definition for new AArch64 machine
type, a work-around is added to correctly flag 64-bit ARM libraries.

The patch doesn't seem to apply against master? Master appears to have
an additional patch than the list above?
