Log:
        PR c++/92576 - redeclaration of variable template.

The variable templates patch way back when forgot to add handling here.  The
simplest answer seems to be recursing to the underlying declaration.

        * decl.c (redeclaration_error_message): Recurse for variable
        templates.
