This patch consolidates the epoll_wait Linux syscall generation on sysdeps/unix/sysv/linux/epoll_wait.c. The implementation tries to use __NR_epoll_wait if defined, otherwise calls epoll_pwait. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/epoll_wait.c: New file. * sysdeps/unix/sysv/linux/generic/epoll_wait.c: Remove file. * sysdeps/unix/sysv/linux/syscalls.list: Remove epoll_wait from auto-generation list.
