    cross.bbclass: override TARGET_* flags
    
    Some TARGET_* flags are being exported in bitbake.conf currently, so
    they are impacting all the tasks of a cross recipe even they are not
    in use at all.
    
    This can lead a lot of churn when the cross sysroot are shared by
    machines while they have defined different TARGET_* flags.
    
    And sometimes it even causes "Taskhash mismatch" errors.
    
    Fix it by overriding with BUILD_* flags.
