Asiri Rathnayake 54387eef07 Introduce a native-only unwinder build. ... Currently libunwind is built to support cross-unwinding [1] by default, which requires the buffers unw_context_t and unw_cursor_t to be large enough to hold the vritual register set (VRS) of any supported architecture. This is not desirable for some platforms where the stack usage of the unwinder needs to be kept to a minimum (e.g. bare-metal targets). The current patch introduces a native-only (-DLIBUNWIND_ENABLE_CROSS_UNWINDING=OFF) unwinder variant that adopts strict sizes for the buffers unw_context_t and unw_cursor_t depending on the target architecture.
