Does LD_32_LIBRARY_PATH not work for you?
Another idea would be to modify rtld-elf to automatically
replace "lib" with "lib32" inside rpath strings when
executing i386 binaries on an amd64 system. This would
be a rather trivial change, just one line in rtld.c.
But I haven't actually tried this. LD_32_LIBRARY_PATH
works for me.
