Thank you very much for your feedback.  I really appreciate it.

Referring to the other thread for context
(https://gcc.gnu.org/ml/gcc-help/2019-05/msg00154.html), I think the
DEB packager has a patch for this problem because `debuild' uses both
the switch --enable-libstdcxx-debug and the `profiledbootstrap' target
successfully.  I am trying to fish that patch out of the patches under
`debian/patches' directory.  I will report back.

Best regards,
