I think the machinery is broken.  This did not happen with checkouts from
a few days ago.  I just did a fresh checkout and bootstrap of the
mainline, and the same problem exists there too.

It looks like quite a few changes to libstdc++-v3 occurred in the past few
days, so I'm suspecting the problem might be there somewhere, but I'm
not sure....
