Subject: [PATCH] CM_OVERRIDE: fix feature test for clang

Clang refuses to default initialize an instance of a class that does not
have a default constructor.  Fix the check by adding default
constructors.  Don't use brace initialization like it is proposed in the
error message.  We want to test the override support independent from
the support for brace initialization.
