Fix compilation with 4.x kernel headers
- Fallback to __NR_stat syscall in ld.so if we use 4.x kernel headers. 4.x kernel doesn't support 64-bit time so we can use old syscall - Add preprocessor conditions to have fstat64 and fstatat64 in libc with old kernel headers Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
