Mao Han 6bbfc5c09f 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.

README 

This hierarchy supports Linux systems using the new
asm-generic/unistd.h, which removes many familiar old syscalls.  For
example, to implement open(), newer Linux architectures require glibc
to invoke the __NR_openat syscall with AT_FDCWD.  This hierarchy
provides all those implementations.

It also provides support for 32-bit platforms using the 64-bit kernel
syscall APIs, as the 32-bit ones are no longer provided.  Note that
newer ILP32 environments (x32 or AArch64:ILP32, for example) are
converting to use more 64-bit types in kernel syscalls, so that aspect
of this support is in more flux as of this writing.
