That's a wrong layout. Really. If Ubuntu alone did this mess it's
definitely worth a bugreport. See what the official AMD64 ABI [*] says:

===
A.1 Execution of 32-bit Programs
The AMD64 processors are able to execute 64-bit AMD64 and also 32-bit
ia32 programs. Libraries conforming to the Intel386 ABI will live in the
normal places like /lib, /usr/lib and /usr/bin. Libraries following the
AMD64, will use lib64 subdirectories for the libraries, e.g /lib64 and
/usr/lib64. Programs conforming to Intel386 ABI and to the AMD64 ABI
will share directories like /usr/bin. In particular, there will be no
/bin64 directory.
===

Fortunately there _are_ distros that get it right ;-)
