[Automake-NG] [FYI] {ng/master} compat: restore support for $(INCLUDES) variable

[Stefano Lattarini]

With the aim of avoiding the introduction of too much unneeded
differences and incompatibilities between Automake-NG and
mainline Automake.

See also commit v1.13.1b-166-g57c7200 (2013-04-19, compat: reinstate
support for obsolete $(INCLUDES) variable) in mainline Automake.

* automake.in (generate_makefile): The definition of the INCLUDES
variable now causes a warning in the 'obsolete' category rather than
a fatal error.
* NG-NEWS: Adjust.
