[Automake-NG] [FYI 4/4] [ng] dist: less use of transforms, prefer make variables (4)

[Stefano Lattarini]

* automake.in (preprocess_file): Turn the '%CK-NEWS%' transform into ...
(generate_makefile): ... the '$(am.conf.check-news)' internal variable.
* lib/am/distdir.am (distdir): Adjust accordingly.
