[External] : platform.m4 old CPUs

[Baesken, Matthias]

Hello, we still have in platform.m4 handling for old CPUs like


    alpha*)
      VAR_CPU=alpha
      VAR_CPU_ARCH=alpha
      VAR_CPU_BITS=64
      VAR_CPU_ENDIAN=little
      ;;

    sparc)
      VAR_CPU=sparc
      VAR_CPU_ARCH=sparc
      VAR_CPU_BITS=32
      VAR_CPU_ENDIAN=big
      ;;
    sparcv9|sparc64)
      VAR_CPU=sparcv9
      VAR_CPU_ARCH=sparc
      VAR_CPU_BITS=64
      VAR_CPU_ENDIAN=big
      ;;
    sparc)
      VAR_CPU=sparc
      VAR_CPU_ARCH=sparc
      VAR_CPU_BITS=32
      VAR_CPU_ENDIAN=big
      ;;

Is this still needed ?

Thanks, Matthias
