uClibc declares eventfd() as taking two arguments but doesn't properly
pass the second argument to the kernel.
The problem is discussed at:
http://lists.uclibc.org/pipermail/uclibc/2012-May/046873.html
This patch is taken from uclibc 0.9.33 git, so will presumably
be integrated in any future releases.
