Backported from the below upstream commit by Timo Teräs. Changes
to non-header files were removed.
From b8f1f91cc6d7b579fdb2370ab046565f9930aa09 Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>
Date: Wed, 7 Oct 2009 22:51:55 -0400
Subject: [PATCH] clean up O_CLOEXEC handling
Drop the "#ifndef O_CLOEXEC" cruft, enable O_CLOEXEC in most fcntl.h
headers, and import __ASSUME_O_CLOEXEC from glibc.
