Yes, I've seen this in cross-network builds when the source
is updated on one system and built on another system when the
clocks are not synchronized.

Source, build, and install are all on the same mounted file system.

This is running in a VM.  As far as I can tell, time is in sync.

I built glibc last week on this system with no problem.
This behavior just started a day or two ago. I modified glibc and
running make didn't terminate.  I've backed out all my changes.
