On some architectures one can be running a 64-bit kernel with a 32-bit userland. Such is the case for sparc64 (unsupported) for example and mips64 with n32 ABI. Some tools that interface directly with the kernel need to be built specially for this, so introduce this symbol to tweak their build in one central kludge to be future-proof. Example: bug #6602.
