| 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. |
