The usual idiom in the rest of automake is to use something like this
for update-only-if-changed files:
version.texi: stamp-vti
@if test -f $@; then :; else rm -f $@; $(MAKE) stamp-vti; fi
Along with dealing with 'rm version.texi; make', this also ensures that
make executes some commands, thus preventing it from caching the
timestamps on version.texi.
I believe automake should use this idiom here too.
