I'm still using the release tree, but I've modified my patches to add a
<bits/kernel-features.h> containing the symbol glibc uses, and use that file.

I'm attaching the part of the patch that works on poll.h.  

The patch that adds kernel-features.h would not apply on top of an existing
kernel-features.h, so it's not included.  The symbol is __ASSUME_POLL_SYSCALL,
and I set it to apply on 2.2.0 or higher.  (Glibc turns it on at a precise 2.1
release I don't recall off hand.)
