Glibc 2.7 doesn't contain timerfd, signalfd, and eventfd.  If your
kernel supports them, I think you can use Sheepdog by defining all
relevant functions and structures, for example, as follows.

#define __NR_signalfd 282

int signalfd(int fd, const sigset_t *mask, int flags)
{
	return syscall(__NR_signalfd, fd, mask, flags);
}


Thanks,
