Richard,

I was able to reproduce this consistently on my build server which has 24 cores running at 3.5 GHz.  I was using:

BB_NUMBER_THREADS = "24"

And

PARALLEL_MAKE = "-j 24"

I can try a build reducing the number of threads and see if the issue goes away as this might be a difference between our builds.  Can you tell me what you are using?

It seemed like a race condition because after I got the error I was able to do a -c cleanall of libtool and kick off the build again once libtool-cross was built and it would pass.  Likewise I did:

bitbake libtool-cross
bitbake libtool

and that would work but just

bitbake libtool

would fail.
