[PATCH] sparc64: Fix stat
Like Alpha, sparc64's struct stat was defined before we had the
nanosecond et al. fields added. So like Alpha I have to cons up a
struct stat64 to get this stuff. I'll work on the glibc bits soon.
Also, we were forgetting to fill in the nanosecond fields in the sparc
compat stat64 syscalls.
