[PATCH] sparc64: Fix stat

Browse source 
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.
