[Bug translator/6977] Incorrect resolution of variables in function scope

[prerna at linux dot vnet dot ibm dot com]

This arises because the variable "zone_reclaim_mode" is a global variable
defined in a different compilation unit than that of the function
"get_page_from_freelist()"
The Dwarf entry for "zone_reclaim_mode" in the CU of the function is simply a
declaration which doesnt have location info for it (since the variable is
defined as an extern int in this CU). This causes a semantic error when the stap
translator tries to fetch DWARF location info from its declaration.

To me, it appears similar to the problem of trying to access a global variable
in a different compile unit than the one in which it is defined.
