The old way called symtab_finalize before the is_static pass,
causing a problem since symtab_finalize uses is_static as part of
its address conflict resolution algorithm. Since global symbols
were prefered over static symbols, and all line symbols were
global at that point, static function names that conflicted with
their own line numbers (static, but labeled as global) were
rejected in favor of the line num.
This was not the desired functionality. We always want to keep
our function symbols and discard any conflicting line symbols.
Perhaps symtab_finalize should be modified to make this
