Antonio Borneo 4fc0f3530c Makefile.am: fix non-POSIX warning from automake ...

Automake issues a warning
	Makefile.am:46: warning: wildcard $(srcdir: non-POSIX variable name
	Makefile.am:46: (probably a GNU make extension)
because the GNU make function 'wildcard' is not POSIX.
Also the GNU make function 'shell' triggers a similar warning.

Use the POSIX extension '!=', that executes an arbitrary shell
command, to replace the GNU make 'wildcard'.
Don't include the file 'NEWS' because automake already includes it
by default.
