I think the conclusion was that having a NOSTRIP flag in the object file
is far from trivial, because what "strip" means for several people and
tools is not clear.

So I guess we are stuck with the old keep-a-list method.

Or we may add NOSTRIP meaning "_never ever_ strip this section, period,
no matter what."
