[PATCH] Use XSTAT_IS_XSTAT64 in generic xstat functions

[Steve Ellcey]

Here is a new version of my patch to use XSTAT_IS_XSTAT64 in generic 32
bit xstat routines. Â This is needed for the aarch64 ILP32 work where
the xstat and xstat64 routines can be aliased. Â This patch uses #if's
instead of #ifdef's since my earlier patch defined XSTAT_IS_XSTAT64 to
0 or 1 in all of the kernel_stat.h header files.

Tested on x86 and aarch64. Â OK to checkin?

        fxstat if XSTAT_IS_XSTAT64 is set to non-zero.
        * sysdeps/unix/sysv/linux/generic/wordsize-32/fxstatat.c: Ditto for
        fxstatat.

        lxstat.
        * sysdeps/unix/sysv/linux/generic/wordsize-32/xstat.c: Ditto for xstat.

        * sysdeps/unix/sysv/linux/generic/wordsize-32/fxstat64.c: New file.

        * sysdeps/unix/sysv/linux/generic/wordsize-32/lxstat64.c: Make __lxstat
        an alias of __lxstat64 if XSTAT_IS_XSTAT64 is set to non-zero.
