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

It seems that the desired build configuration works also as expected on my
system with an out-of-source build after a small adjustment for a variable.

 AM_INIT_AUTOMAKE


I have got the impression that there are more update candidates to consider
since the macro call "AM_INIT_AUTOMAKE" was added.

- Would you like to drop the variable "COCCI_SRCDIR" eventually (because there
is a standard one available)?
- How do you think about to change comments in files like "Makefile.am"?
