I suspect it would be possible to solve by splitting the timestamps into 
two different files. One is the VERSION file determining when autoconf 
needs to be run and a timestamp file determines when the version.sh 
script needs be run. Something like:

CONFIGURE_DEPENDENCIES = $(srcdir)/VERSION

$(srcdir)/VERSION:
  rm -f timestamp && $(MAKE) $(srcdir)/timestamp

$(srcdir)/timestamp: ChangeLog
  cd $(srcdir) && $(SHELL) version.sh packageversion && :> $@

I think that works as long as the timestamp is "included" in 'make all' 
early by using BUILT_SOURCES, or if EXTRA_DIST suffices.
