Hmm, now I have arrived at the conclusion that non-odr-used variables might
require the definition, depending on compiler options etc., and this PR is
invalid, since there is no guarantee in the specification that
non-odr-used-ness of variables makes the definition unnecessary.

I'm sorry. I created this PR based on the wrong assumption. I should have
created a PR reporting the bug in libstdc++. And thank you for the quick fixes.

Again, thank you for your time.
