Add support for the Signal Processing Engine.
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.

help
EGLIBC (Embedded GLIBC) is a variant of the standard GNU GLIBC
that is designed to work well on embedded systems. EGLIBC strives
to be source and binary compatible with GLIBC. Its goals include
a reduced footprint, configurable components, and improved
cross-compilation support. EGLIBC also includes some embedded ports
(such as e500/spe) that are normally separate add-ons of GLIBC.
