These shall only be added iff `PREFER_STATIC` is not set.

By default all libraries and applications that can be dynamically linked
will be dynamically linked. You can override this behaviour by setting
the `COOKBOOK_PREFER_STATIC` environment variable. Note that if you
perviously did not use this flag, it might (most likely will) require a
complete userland sysroot recompilation.

It will look like this:
```bash
$ make clean
$ COOKBOOK_PREFER_STATIC=yes make image
```

For testing, the following will also work:
```bash
$ COOKBOOK_PREFER_STATIC=yes make cr.{PACKAGE_NAME} # obviously replace
                                                    # PACKAGE_NAME with
                                                    # the name of a package :)
```

We also statically build as cosmic-files requires it.
