This patch fixes a warning seen with gcc 4.8 (especially on ubuntu 13.10)

| addr2line.c: In function 'handle_address':
| addr2line.c:450:7: error: format '%a' expects argument of type 'float *', but argument 3 has type 'char **' [-Werror=format=]
|        if (sscanf (string, "(%a[^)])%" PRIiMAX "%n", &name, &addr, &i) == 2
|        ^
| addr2line.c:453:7: error: format '%a' expects argument of type 'float *', but argument 3 has type 'char **' [-Werror=format=]
|        switch (sscanf (string, "%a[^-+]%n%" PRIiMAX "%n", &name, &i, &addr, &j))
|        ^
| cc1: all warnings being treated as errors


%a is old GNU style and should be abandoned in favor of %m

Also see

to support this assertion

This patch is added via redhat-compatibility patch so lets revert this part
here.
