Ah, ok, then it is clear what happened: when you checked out,
time stamps of the files may have caused the autotools reruns.
It's difficult to prevent.

So what happens then is that the rerun commands don't work
unless a bootstrap has run before at least once.

We could certainly remove generated files from git.  If they
pose very big problems, then we may consider this.  However,
especially for developing Automake it's sometimes good to see
how changed affect the generated Makefile.in files.
