The package is glibc-2.12-1.107.el6_4.5.x86_64.

I just retried the compilation, and poll.h is attached. It contains
#if 1
# include_next <poll.h>
#endif

There is a /usr/include/poll.h, which contains the one line
#include <sys/poll.h>
This in turn does an
#include <bits/poll.h>
which has a line
#define POLLIN          0x001           /* There is data to read.  */

I tried to replace the # include_next in lib/poll.h by a simple #include,
but that leads to
../lib/poll.h:31:18: error: #include nested too deeply
