+
+Change location where GOT information is collected for ARC target, avoiding
+posible use conflicts of the previous .got field in the symbols hash_entry.

+
+Problem identified in the context of glibc with latest upstream binutils.
+Dynamic symbol space was being reserved but, no actual information for the
+symbol was being set. Data for the symbol was kept initialized with -1.
+No easy test case was possible to be created.
