fstatat64: define it as a wrapper of statx if the kernel does not support fstatat64 syscall
Define fstatat64 as a wrapper of statx if the kernel does not support fstatat64 syscall This is the case for non-legacy architectures that don't define __ARCH_WANT_NEW_STAT in their linux arch/xxx/include/asm/unistd.h Signed-off-by: Yann Sionneau <ysionneau@kalray.eu>
