commit 6bbfc5c09fc5b5e3d4a0cddbbd4e2e457767dae7
Author: Mao Han <han_mao@c-sky.com>
Date:   Mon Nov 26 11:13:32 2018 +0800

    Add statx conditionals for wordsize-32 *xstat.c
    
    Linux kernel have remove stat64 family from default syscall set, new
    implementations with statx is needed when __ARCH_WANT_STAT64 is not
    define. This patch add conditionals for relevant functions, using statx
    system call to get information and then copy to the return buf, ref to
    include/linux/fs.h from linux kernel.
    
    	* sysdeps/unix/sysv/linux/Makefile: Add statx_cp.c.
    	* sysdeps/unix/sysv/linux/fxstat64.c: Add conditionals for kernel
    	without stat64 system call support.
    	* sysdeps/unix/sysv/linux/fxstatat64.c: Likewise.
    	* sysdeps/unix/sysv/linux/generic/wordsize-32/fxstat.c: Likewise.
