    arm64 fixup for statx support on older kernels
    
    Turns out (older) arm64 linux kernels don't have statx, but also not
    stat64 and no stat syscalls.  It uses fstatat instead. The new statx
    patch also added a check for stat.  So That needs a special case for
    arm64.
    
    Follow up for bug #400593.
