for now I reverted this. Things get too complicated when we have to
conditionally export some symbols depending on the target (see
libstdc++/61536).
Thanks,
Paolo.

A single extra symbol (for the unusual -O0 compilation) is better than 200
before the patch though. I think the patch is a good thing (also for
future-proofing) even if one or two extra symbols remain because they are
hard to remove. Also, none of this is urgent, it can all wait several
weeks if you are busy.
