[PATCH 5/6] bison: use no-lines

[Akim Demaille]

The 'regen' commit in Bison's history are a nuisance.  They are
especially big because of the #lines.  Let's generate our parse
without these lines in the repository, but generate them in the
tarball.

* Makefile.am (AM_YFLAGS_WITH_LINES): New.
(AM_YFLAGS): Use it.
(dist-hook): Regenerate the parser with #lines.
