Subject: [PATCH] Make sure global symbol is not an indirect or warning.

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.
