timespec::tv_nsec is going to be 64-bit wide even on 32-bit architectures. As not all architectures support 64-bit division instructions, calls to libgcc (__divdi3()) may be emitted by the compiler which are not provided by nolibc. As tv_nsec is guaranteed to always fit into an uint32_t, perform a 32-bit division instead.
