* symbols therefore no symbols are added and the only ones are part of the
* relocation records to bind to base image symbols. Another case is the
* need for an application to export symbols because it is using dlopen to
* load modules. Here the symbols maybe 'all' or it could be a user
* maintained list that are exported.
*
* @param app The application image to write too.
* @param init The application's initialisation entry point.
* @param fini The application's finish entry point .
* @param objects The list of object files in the application.
* @param symbols The symbol table used to create the application.
