Oh dear.  Sorry about that.

I guess the attached is the fix?

Subject: [PATCH] Don't include stdio64 functions in reentrant syscalls menu
 when not bulding stdio64.

Fix documentation build since 6c2b1842 by not included stdio64 functions in the
reent syscalls menu if the node itself isn't going to be included because it's
under the STDIO64 flag.
