is also the underlying requirement to support built-in applications in the

---help---
Hidden option indicating that the compile-time name/priority/stacksize
registry table for applications (struct builtin_s / g_builtins[]) is
available. This is a broader condition than BUILTIN: BUILD_KERNEL
cannot select BUILTIN (main_t dispatch is meaningless when the caller
and the application are in different address spaces), but it still
needs this table so that posix_spawn() can pick up each application's
configured priority and stack size.
