Runtime isn’t the issue. The problem is the ubuntu store failing the snap
in the automated tests after the upload.

Not sure I understand your question. But the snap upload is the main one
complaining and failing the the snap in the automated test because of the
reference.
I thought that libc6 would be an exception and doesn’t need to be added to
the snap.

I thought this should be a common issue from other snap’s (and expected
known solutions). Or how do other C projects solve this?
