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. * sysdeps/unix/sysv/linux/generic/wordsize-32/fxstatat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/lxstat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/lxstat64.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/xstat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/xstat64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/statx_cp.c: New file. * sysdeps/unix/sysv/linux/statx_cp.c: Likewise. * sysdeps/unix/sysv/linux/statx_cp.h: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/statx_cp.c: Likewise.
