Oh. Bing bing bing. Of course.
You can use libc.12.40 with a kernel of corresponding age and an
otherwise old system, but you can't use libc.12.40 with an old kernel
regardless of the rest of userland. In particular, you can't drop
libc.12.40 into an otherwise bog-standard old system and have it work.
My apologies for the confusion.
