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.
