Thread options & clone events (native Linux)
This commit teaches the native Linux target about the GDB_TO_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 report support for the option, otherwise GDB falls back to use
target_thread_events().
