(1) Keep the `.init_array` and `.ctors` symbols and sort them according to their initialization priority. (2) Exclude symbols ending with crtend.* and crtbegin.* to support c++ application.if we not exclude crtend.* crtbegin.* frame_dummy will be added when enable any c++ application with global variables, this symbol execution is problematic, removing it does not affect the application.
