/*
 * Linker wrap stub for __cxa_atexit().
 *
 * GCC registers the destructor of every global and function local static
 * object with __cxa_atexit(). The firmware never returns from main or calls
 * exit(), so these destructors never run, but the first registration links
 * newlib's exit handler tables.
