unwind: disable RTTI during the build of libunwind
Disable the type information emission for libunwind. libunwind does not
use `dynamic_cast`. This results in a smaller binary, and more
importantly, avoids the dependency on libc++abi. This ensures that we
have complete symbol resolution of symbols on ELF targets without
linking to the C++ runtime support library. This change avoids the
emission of a reference to `__si_class_type_info`.
