extern string addr is not loaded in cle

[ducorduck]

Description

i guess you're already aware of the bug. in various_variable.c extern char string[]; in line 83, the address is not loaded from cle.

Example can be found in test_dwarf_variable.py in method test_variable_scopes.

Thanks!

Note that this is a very rare corner case (that one introduces an extern variable with local visibility in a function). Furthermore, a fix seems to be difficult, so I add the wontfix label.
