Eelco Dolstra 6c98e6a5de Optionally ignore null-valued derivation attributes ...

This allows adding attributes like

  attr = if stdenv.system == "bla" then something else null;

without changing the resulting derivation on non-<bla> platforms.

We once considered adding a special "ignore" value for this purpose,
but using null seems more elegant.
