LD_LIBRARY_PATH is for native 64bit rtld. If you want a specific path
added for use by 32-bit ld-elf.so.1 only, use LD_32_LIBRARY_PATH.
Said that, your problem is likely caused by the fact that there is
no /lib32, only /usr/lib32. So if 64-bit library lives in /lib,
your LD_LIBRARY_PATH will cause loader to find its 32-bit equivalent
in /usr/lib32 first.
Try LD_LIBRARY_PATH=/lib:/usr/lib:/usr/lib32:/usr/lib64 for better
