Comment:
It just didn't work for me without them. If `lib/vdso/Makefile` is not present, the result is this:

```

Subsequently, `gettimeofday.c` is required. I'm running it on an RPi4B with aarch64. Maybe running a 32-Bit architecture it's not required? [In the template vdso seems to get handled separately for aarch64](https://github.com/classabbyamp/void-packages/blob/update/rpi/srcpkgs/rpi-kernel/template#L233).
