Use Gnulib's `git-version-gen'.

* GUILE-VERSION (GUILE_VERSION): Remove.

* Makefile.am (dist-hook): Depend on `gen-tarball-version'.
  (BUILT_SOURCES): New variable.
  ($(top_srcdir)/.version, gen-tarball-version): New targets.

* cfg.mk (git-version-gen-tag-sed-script): New variable.

* configure.ac: Use `build-aux/git-version-gen' to generate the VERSION
  argument of `AC_INIT'.  Initialize Automake without `check-news'.
  Define $GUILE_VERSION as an alias for $PACKAGE_VERSION.

-dnl  `patsubst' here deletes the newline which "echo" prints.  We can't use
-dnl  "echo -n" since -n is not portable (see autoconf manual "Limitations of
-dnl  Builtins"), in particular on solaris it results in a literal "-n" in
-dnl  the output.
