    Fix issues with gold undefined symbol diagnostics.

    PR binutils/15435 complains that gold issues a visibility error for an
    weak undefined symbol with hidden visibility. The message should be
    suppressed if the symbol is a weak undef.

    An earlier patch to add an extra note about key functions when a class's
    vtable symbol is undefined missed a case where the reference to the
    vtable came from a shared library. This patch moves the check to a
    lower-level routine that catches both cases.

        * errors.cc (Errors::undefined_symbol): Move undef vtable symbol
        check to here.
        * target-reloc.h (is_strong_undefined): New function.
        (relocate_section): Move undef vtable symbol check from here.
        Check for is_strong_undefined.
