uClibc: Backport uClibc master git commit fd355bc1dbcb794ae1abf0fad1459e28d8567ba0 (eventfd.h: Use new "bits/" scheme for arch-specific flags) 

This patch adds missing architecture-specific headers for use with
eventfd(2). Fixes #16679.

From fd355bc1dbcb794ae1abf0fad1459e28d8567ba0 Mon Sep 17 00:00:00 2001
From: Hiroaki KAWAI <kawai@stratosphere.co.jp>
Date: Fri, 19 Apr 2013 01:09:35 +0000
Subject: eventfd.h: Use new "bits/" scheme for arch-specific flags
As in timerfd.h, eventfd.h needs arch-specific definition files.
alpha, mips and sparc needs separate file, all the other arch
will use common definition.
This problem is already fixed in glibc.
Also sanitize and provide bits for hppa.
Make sure not to install the new bits/eventfd unless eventfd support is
enabled.
