Object files lack dependency on `config.h` symlink (and usually depend
only on `ldns/config.h`). As a result build occasionally fails in
`make --shuffe mode`:
$ make --shuffle
...
./libtool --tag=CC --quiet --mode=compile gcc -I. -I. \

The change moves `config.h` symlink creation in `setup-builddir` from
a dependency on final binary to dependency on all individual objects.
While at it regenerated dependencies with `make depend`.
before the change `make --shuffle` build was failing in about 50% cases.
After the change: `make --shuffle` succeeded 80 times in a row.
