autogen.sh is expected to be run once after checking out a new tree.
After that, "make" should take care of rebuilding configure if/when
needed, so the dependencies all seem right.

Indeed in this situation they don't help but neither do they hurt.
And they do help when you run "make" after configure.in was modified.
