whose <literal>system</literal> attribute equals the value
specified here. In general, it never makes sense to modify this
value from its default, since you can use it to ‘lie’ about the
platform you are building on (e.g., perform a Mac OS build on a
Linux machine; the result would obviously be wrong). It only
makes sense if the Nix binaries can run on multiple platforms,
