Yes, I also found it. Thank you.

I think I shared the link too soon, and patches should be revised 
again. So I continue the work on it. If you curious, find it here.
https://github.com/norov/glibc/tree/ilp32-dev
(I don't promise I'll keep it stable, or will avoid using things like
fast-forward. It's just a branch for my experiments.)

For now, it has fixed:
 - __ilp32__ mess (by introducing DELOUSE() macro);
 - few unneeded patches dropped;
 - 32-bit off_t turned to 64-bit.

With all changes, LPT fail list grows:
