Akim Demaille 4fd1fc70e0 examples: ship them ...

Currently, the examples are extracted on the user's side.
Unfortunately, that requires that the user has Perl, which is
otherwise not needed for Bison.  Let's ship the examples instead.

The examples were handled this way so that we could depend on
configure flags: if --enable-gcc-warnings is passed, it is understood
as "I'm a maintainer", so the examples are generated with `#line`s.
Regular users should not see them, so they are now unconditionally
removed when rolling a tarball.

* examples/local.mk: Ship all the extracted files.
(examples-unline): New.
Make sure that the generated tarballs do not contain the #lines.
