Do we actually need this?

I'd rather let it bitrot, and just let it return random versions. It
will just start again at 2.4.60, won't it?

Anybody who uses UNAME26 for a 5.x kernel might as well think it's
still 4.x. The user space is so old that it can't possibly care about
differences between 4.x and 5.x, can it?

The only thing that matters is that it shows "2.4.<largeenough>",
which it will do regardless.
