elflint allows the sillyness of marking out the bounds of the section.
That is precisely what happens here, the symbol is used to mark the
end of the section (section_size), but then the whole section that
the symbol is associated with is removed. So now the symbol is
associated with some other random section, and points into some other
one that now is associated with the address of the symbol. In that
case it seems natural to at least mark the symbol as being associated
with SHN_ABS as Richard did, but it would be even better if ld didn't
just toss out a section that has symbols associated with it, so that
the address of the symbol at least matches up.
