The failure is here.  I suspect this might be yet another timestamp issue.
Could you please answer the following questions?

  1. Is your system quite fast? (I'd assume yes, given the contents of
     config.log)

  2. Does the directory you are building Automake into have sub-second
     timestamp resolution?

  3. Does the reported failure happen consistently, or is it subject to
     a race?

If the answers to the questions above are respectively "yes", "no" and "yes
it's a racy failure", then I think the attached patch might fix the issue.

Regards,
  Stefano
