Oh, and if people really are using "uname()" to figure out that they
are running a 64-bit kernel, then we should probably make uname() use
"is_compat_task()" instead of checking the PER_LINUX32 personality.

So we already do have support for returning a different machine-name
to 32-bit binaries, but it uses the "personality" thing that nobody
cares about, rather than the compat layer. Looks like purely
historical reasons.
