    Remove i386/epoll_pwait.S

    Only i386 implements epoll_pwait in assembly code withot cancellation
    support.  All other architectures implement epoll_pwait in epoll_pwait.c
    with

    int epoll_pwait (int epfd, struct epoll_event *events,
                 int maxevents, int timeout,
                 const sigset_t *set)
    {
      return SYSCALL_CANCEL (epoll_pwait, epfd, events, maxevents,
                         timeout, set, _NSIG / 8);
    }

    Although there is no test for epoll_pwait in glibc, since SYSCALL_CANCEL
    works on i386 and epoll_pwait.c works for other architectures, it is
    safe to assume that epoll_pwait.c with SYSCALL_CANCEL also works on
    i386.

        [BZ #19137]
        * sysdeps/unix/sysv/linux/i386/Makefile (CFLAGS-epoll_pwait.c):
        Add -fomit-frame-pointer.
        * sysdeps/unix/sysv/linux/i386/epoll_pwait.S: Remove file.
