Nikita Smith d3dedd8bef simplifying symbol table scopes
Linker cannot register extern import symbols initially because
the import object files are not available until all other object files are
resolved. To work around this, we create a stub weak symbol and assign
it to each import symbol. This allows linker to proceed. Once the import
object files are generated, linker replaces the stub symbol with
the actual ones from the import objects.
