Thread options & clone events (native Linux)
This commit teaches the native Linux target about the
GDB_THREAD_OPTION_CLONE thread option. It's actually simpler to just
continue reporting all clone events unconditionally to the core.
There's never any harm in reporting a clone event when the option is
disabled. All we need to do is to report support for the option,
otherwise GDB falls back to use target_thread_events().
