[gold patch obvious] Fix internal error with --output-symbol-counts

[Cary Coutant]

The --output-symbol-counts option in gold can trigger an internal
error when a global symbol from a shared object does not appear in the
dynamic symbol table. I'm applying this trivial patch to fix the
problem.

Tested on x86_64.
