The entire section table on a DSO is not really significant. The only
part that is required is some way to get the symbol table, and only that
just for static linking.

The table is mostly a human friendly info showing where a section
"is". The situation is fuzzy with NOBITS, but I think the customary is
to use the location they would have been had they not been NOBITS.
