yann@815:       Add support for the Signal Processing Engine.  This will set up
yann@815:       the toolchain so that it supports the SPE ABI extensions. This
yann@815:       mainly targets Freescale e500 processors.
yann@815: 
yann@815:       Setting this option will append "spe" to the end of your target
yann@815:       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@815:       configure/build system will know to include SPE ABI support.
yann@815:       It will also automatically add "-mabi=spe -mspe" to your
yann@815:       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
yann@815:       so you do not need to explicitly add them.
