Subject: Fix max-depth test case for AIX.

Fix max-depth test case for AIX.

In AIX, if in the main program the global variables are unused then the linker optimises
these variables and the dwarf will not have proper address to the same. Hence we cannot access these
variables.

This patch is a fix to the same so that all the test case of max-depth can passs in AIX as well.
