That's not the right fix.  That code should only be used if gold is
using <ext/hash_map>, which is a fall back for older compilers.
Currently gold prefers <tr1/unordered_map>.  I think we need to add a
case to configure.ac and system.h to use <unordered_map> if it is
available, as I assume it is for libc++.
