Subject: [PATCH v2 06/13] tools/nolibc: add pure 64bit off_t, time_t and blkcnt_t
clean up std.h with include/uapi/linux/posix_types.h
convert time_t to 64bit even in 32bit platforms, for y2038 issue.
align off_t and blkcnt_t with 'struct statx' in include/uapi/linux/stat.h
Suggested-by: Arnd Bergmann <arnd@...db.de>
