    x86/legacy: fix subtarget CPU for kernel 5.10
    
    The 5.10 target config defined a baseline i686 CPU aligned to the 32-bit
    generic subtarget. However, the legacy subtarget arch wasn't set to the
    older 586MMX, defaulting instead to the i686.
    
    Explicitly set the subtarget arch and refresh the subtarget config, as done
    already with the old geode subtarget.
