Are you using Automake?  If yes, and if the arguments to AC_CONFIG_FILES
are shell literals, then automake should produce a rule to regenerate
the file for you.

Otherwise, you can also just add one to your makefile, a la

  git_version: $(top_builddir)/config.status git_version.in
        cd $(top_builddir) && ./config.status $(top_build_prefix)$@

(untested, you could look into the manual if you need more information).
