      Add support for the Signal Processing Engine.  This will set up
yann@1634
     9
      the toolchain so that it supports the SPE ABI extensions. This

      mainly targets Freescale e500 processors.

      Setting this option will append "spe" to the end of your target
yann@1634
    13
      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@1634
    14
      configure/build system will know to include SPE ABI support.
yann@1634
    15
      It will also automatically add "-mabi=spe -mspe" to your
yann@1634
    16
      TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
yann@1634
    17
      so you do not need to explicitly add them.
