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.
