Title:
  Unable to use dynamic_cast (no RTTI)

Status in Cheerp:
  Fix Released

Bug description:
  class A { public: virtual ~A() {} };
  class B : public A { public: virtual ~B() {} };
  A *a = dynamic_cast<B*>(new A);

  
  HelloClient.cpp:61:12: error: cannot use dynamic_cast with -fno-rtti
      A *a = dynamic_cast<B*>(new A);

  RTTI is disabled by default, is possible to enable it somehow? I want
  to port some codes in duetto however I need RTTI.
