Yes: it's part of the psABI.  Debian decided not to follow it, and
presumably they have a patched gcc.

"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."
