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.

+%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.
