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.

Good catch! I'm wondering if this one shouldn't be marked as a build fix for 5e7392dc82ed ("tools/nolibc: fall back to sys_clock_gettime() in gettimeofday()") so that it can be backported.
