The global variables generated to store this_image/num_images were wrong in
several ways:

- translation-unit (TU) dependent name (could be same or different)
- variable generated in every TU - and not only in one
- not pushed - which could cause already failures with one TU

Now, the variable is generated for the TU of the main program - and in the
others declared as DECL_EXTERNAL, additionally the variable is pushed to make
sure it is generated. Thanks to Jakub for the suggestions!

Build and currently regtesting.
OK for the trunk?

Yes, I think so, considering. ;)
