    build: remove forced -fno-rtti

    * As discussed on the mailing list,
      forced no-rtti breaks C++ public
      API's such as the Haiku C++ libGL.so
    * -fno-rtti *can* be still set however
      instead of blindly forcing -fno-rtti,
      we can rely on the llvm-config
      --cppflags output.
      If the system llvm is built without
      rtti (default), the no-rtti flag will be
      present in llvm-config --cppflags
      (which we pick up on)
      If llvm is built with rtti
      (REQUIRES_RTTI=1), then -fno-rtti is
      removed from llvm-config --cppflags.
    * We could selectively add / remove rtti
      from various components, however mixing
      rtti and non-rtti code is tricky and
      could introduce missing symbols.
    * This needs impact tested.
