That is interesting, and perhaps something I may try when I have the 
time.

In the mean time I am using this simple solution, which works because 
I know what version.sh uses to produce its version (data from itself, 
and from ChangeLog).  I added this to configure.ac:

  AC_SUBST([CONFIGURE_DEPENDENCIES],["$CONFIGURE_DEPENDENCIES
    \$(top_srcdir)/ChangeLog \$(top_srcdir)/version.sh"])

Since the two files always exist, there is no intermediate stuff to 
generate.

I was previously using something similar, but just for config.status:

  AC_SUBST([CONFIG_STATUS_DEPENDENCIES],['$(top_srcdir)/ChangeLog
    $(top_srcdir)/version.sh'])

If the version stamp info came from git or hg, then intermediate 
generated files would surely be required.
