OK, I got it.
I'll try to turn that on.  I was not so clear on what all of the *STAT_IS_*
macros defined, so I was trying to just go with the generic defaults.

On OpenRISC which is only 32-bit XSTAT_IS_XSTAT64 is set to zero.

As per: sysdeps/unix/sysv/linux/generic/kernel_stat.h

    #if __WORDSIZE == 64
    # define XSTAT_IS_XSTAT64 1
    #else
    # define XSTAT_IS_XSTAT64 0
    #endif

Again, I'll see what I can do.
