Can you please try rebuilding GNU make from scratch, giving the option
--disable-nsec-timestamps when you run "./configure"?

I think the problem is that archives are only defined to have timestamps
with second granularity, while your filesystem is storing timestamps
with subsecond granularity.

In the next version of GNU make there's a feature to specify exactly
which targets should and should not use subsecond timestamps, so you can
use them for most targets, but not use them for things like archives
