commit 4d51e8ca64dd4f780781a1280bc7887acc822b33

PR10622. Better workaround for GCC PR51410. Find external var DIE location.
Some GCC versions would output duplicate external variables, one
without a location attribute. If so, try to find the other if it
exists in the same scope. This is a better solution than the previous
fallback solution of just trying to get the address in the symbol table.
That could result in picking the wrong external variable with the same
name (but from a different CU). Add test case to show this works better.
