 available expressions.

-  $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.

 References to target names in generator expressions imply target-level
 dependencies, but NOT file-level dependencies.  List target names with
 the DEPENDS option to add file dependencies.
