Please read it again... even if the optimization flag was
configurable, choosing CONFIG_TINY should *default* the optimization
flag to -Os before it defaults the optimization flag to -O2.

In the case where CONFIG_TINY is an option on its own, it means using -Os
instead of -O2. In the case where CONFIG_TINY is a template *not an option*,
the configurable "optimization flag" gets initialized to -Os. You could
still override -Os to be -O2 if you wanted to, or if CONFIG_TINY was not
specified, you could still override -O2 to be -Os... the default is -Os for
CONFIG_TINY.

K... I don't think this needs any more time.
