+      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,
+      so you do not need to explicitly add them.
