    gprof: Fix strchr discarded qualifier call
    
    In annotate_source strrchr is called on a const char *. So the result
    should also be stored in a const char *.
    
            PR binutils/34125
            * gprof/source.c (annotate_source): Make name_only a const char *.
    
    (cherry picked from commit b8d39fd810e7373aac4f129c34813f6a609d8d5f)
