Rare, but possible: You have a 64-bit capable CPU (e.g., Intel Core 2 or newer) running a 32-bit only kernel (e.g., i386 or i686 PAE). The kernel cannot execute 64-bit ELF binaries because it lacks the CONFIG_IA32_EMULATION in reverse — actually, a 32-bit kernel cannot run 64-bit binaries at all. No emulation layer exists for that.
