Kernel-compile error for walnut with 2.4.18 ?

Hi, all.

I try to comile kernel 2.4.18 for walnut(IBM PowerPC 405GP) board on Red-Hat 7.1. I met below error message and I cannot solve this problem.

powerpc-linux-gcc -D__KERNEL__ -I/home/elecguy/work/ppclinux/linux-2.4.18/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fomit-frame-pointer -fno-strict-aliasing -fno-common -D__powerpc__ -fsigned-char -msoft-float -pipe -ffixed-r2 -Wno-uninitialized -mmultiple -mstring -Wa,-m403 -mcpu=403 -DKBUILD_BASENAME=ppc4xx_pic -c -o ppc4xx_pic.o ppc4xx_pic.c
{standard input}: Assembler messages:

Cross-compiler is builded by following order.

1) binutils-2.12.90.0.1
./configure --target=powerpc-linux --with-cpu=403
make; make install

2) gcc-core-2.95.3
./configure --target=powerpc-linux --enable-shared --enable-languages=c --with-newlib --with-cpu=403
make; make install

linux-2.4.18 with ppc-patch-2.4.18
*in Makefile
ARCH := ppc
CROSS_COMPILE=powerpc-linux-
AFLAGS := -D__ASSEMBLY__ $(CPPFLAGS) -Wa,-m403
*in arch/ppc/Makefile
CFLAGS := (Original flags)... -Wa,-m403
*in make menuconfig
Processor Type -> 4xx
Machine Type -> Walnut

What's wrong?
