PS16, Line 12: the programmer groups individually.
I don't quite understand. What could lead to break the groups if
all at once and every programmer individually work?

The standard way to avoid duplication are functions. Not sure if I missed
anything why that wouldn't work here. Calling site could look like this:
```
single_meson_build all
if [ ${is_scan_build} -ne 1 ]; then
        return
fi
for programmer in ${meson_programmer_opts}; do
        single_meson_build ${programmer}
done
```

Why have `auto` here?
