build: disable RTTI
When using virtual functions while RTTI is enabled, the compiler
generates code to support the use of dynamic_cast etc. This code
requires the use of the free store (heap) which is not yet available.
Disabling RTTI also disables the generation of the associated support
code, thus making it possible for us to use virtual functions.
