file.  The |data| dict provides access to build file dicts.

  Any target that does not wish to be included by wildcard can provide an
  optional "suppress_wildcard" key in its target dict.  When present and
  true, a wildcard dependency link will not include such targets.

  All dependency names, including the keys to |targets| and the values in each
  dependency list, must be qualified when this function is called.
