Add default_binds_local_p_2 and use it for x86

Protected data symbol means that it can't be pre-emptied.  It doesn't mean
its address won't be external.  This is true for pointer to protected
function.  With copy relocation, address of protected data defined in the
shared library may also be external.  We only know that for sure at
run-time.  TARGET_BINDS_LOCAL_P should return false on protected data
