Put all local symbols in object/sym/map files (#774)

Browse Source 
* Store all the local symbols in object files, not only the ones that need linker patches.
  This generates better map/sym files, and thus allows for better debugging as well.

* Add comments explaining the ->src and the (void)arg;
