powerpc/mpc85xx: Improve disabling of SPE instructions
Specifying -mspe=no also disables usage of SPE instructions. It is
documented in "[PATCH,rs6000] make -mno-spe work as expected" email:
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg00311.html
So replace -mspe=yes by -mspe=no, so make it clear that u-boot has to be
compiled without SPE instructions.
Linux kernel contains following Makefile code to achieve it:
# No SPE instruction when building kernel
# (We use all available options to help semi-broken compilers)
KBUILD_CFLAGS += $(call cc-option,-mno-spe)
KBUILD_CFLAGS += $(call cc-option,-mspe=no)
Do same for U-Boot.
