While working on a glibc patch to support the fstatat() functions,
I noticed that the o32 implementation behaves differently on 32-bit and
64-bit kernels; the former provides a stat64 while the latter provides
a plain (o32) stat. I think the former is what's intended, as there is
no separate fstatat64. It's also what x86 does.
I think this is just a case of a compat too far. The o32 stat64 is the
same as plain stat on n64, so 64-bit kernels can just use newfstatat.
(n32 already does this, and works correctly as-is.)
Tested with the glibc patch, where it fixes the test I'd written.
Please install if OK.
 I've seen Khem's patch, but I don't think it's right.
