[Cocci] 1.0.0-rc16: Further fine-tuning for the build system?

I wonder why you do not see the need for corrections in your current build
specification and corresponding configuration scripts so far.

I recommend adjustments for places like the following.
1. A "working directory" should not be referenced by the macro call
'AC_SUBST([COCCI_SRCDIR], ["$(pwd)"])'.

2. I find it strange that OCaml source files are passed in the macro call
'AC_CONFIG_FILES([...])'.

3. How do you think about to rename the extension for the "top level Makefile"
to ".mk"?

4. How would you like to fix the following error message?
   elfring at Sonne:~/Projekte/Coccinelle/Bau> LANG=C make -j6 -f Makefile.config
   make: *** No targets.  Stop.

5. I find that your "Makefile.am" files became inappropriate.
   - outdated comments

   - Which subdirectories should be used?

   - Which source files should be assigned to the variable "spatch_SOURCES"?
     http://www.gnu.org/software/automake/manual/html_node/Program-Sources.html

   - When will the OCaml compiler and linker be called there?
