I don't believe that the doc that you are basing your decisions on is
correct. Anyway, basing such decisions automagically on the
optimization level is very non-obvious. Maybe it is a better idea to
introduce a special build flag (for autotools it would be something
like --disable-running-from-build-tree or --enable-reproducible-build)
that explicitly disables running from build tree and thus enables a
reproducible build?
