Add support for the Signal Processing Engine. This will set up
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
tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
configure/build system will know to include SPE ABI support. It
will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
do not need to explicitly add them.
