elfutils-native: Fix build on distros with gcc 4.8 

The patch redhat-portability.diff causes this issue
so lets revert the portion which was using %a instead of %m
thats recommended anyway, redhat patch seems to be targetting
old compilers.

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
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54361
to support this assertion
This patch is added via redhat-compatibility patch so lets revert this part
here.
