task_fork() is a NuttX extension, not POSIX, and a configuration that does not call it has no reason to carry it. Add CONFIG_TASK_FORK to leave it out. It depends on ARCH_HAVE_TASK_FORK and defaults to y, so it is enabled exactly where fork() existed before the split and no configuration loses the primitive by upgrading. ARCH_HAVE_TASK_FORK keeps its meaning -- the architecture *can* clone the calling task -- and the new symbol says whether this build wants it. Everything that provides task_fork() moves to the new symbol: the declaration in sched.h, up_task_fork() in arch.h, the two .csv entries that generate the system call stub and proxy, the syscall_lookup.h table entry, the architecture entry points, and the build rules for the files that hold them. FORK_IS_TASK_FORK now depends on TASK_FORK rather than ARCH_HAVE_TASK_FORK. Aliasing fork() to a task_fork() that was not built would not link. vfork() and fork() are untouched; each is still selected on its own, and task_fork.c, lib_fork.c and the architecture's fork file are still built when any one of the three is present.
