    Treat common symbol in executable as definition

    Common symbol in executable is a definition, which overrides definition
    from shared objects.  When linker sees a new definition from a shared
    object, the new dynamic definition should be overridden by the previous
    common symbol in executable.

        * elflink.c (_bfd_elf_merge_symbol): Treat common symbol in
        executable as definition if the new definition comes from a
        shared library.
