请教大虾关于“交叉编译环境”的问题

在以下的过程之中，我采用了linux-2.4.21.tar.gz 和 patch-2.4.21-rmk1.gz进行linux头文件的安装。
cd ~/tars/SourceDir
tar zxvf ../linux-2.4.21.tar.gz
cd linux-2.4.21
zcat zxvf ../../patch-2.4.21-rmk1.gz | patch -p1

make mrproper

将Makefile中ARCH := $(shell uname -m | sed -e s/i.86/i386/ -e s/sun4u/sparc64/ -e s/arm.*/arm/ -e s/sa110/arm/) 这一行注释掉，并加一行 ARCH=arm.

因为我用的板子是EP7312的芯片，所以我后面配置了arm720t的processor
cd include/asm-arm
rm -f arch proc
ln -s arch-clps711x arch
ln -s proc-armv proc
cd ../../

make menuconfig

make dep
接下来就出现了问题，具体编译情况如下：
[root@localhost linux-2.4.21]# make dep
rm -f include/asm
( cd include ; ln -sf asm-arm asm)
make[1]: Entering directory `/usr/local/arm/tars/SourceDir/linux-2.4.21/arch/arm/tools'

我想请问一下大虾们，后面出现的那几个invalid option会不会影响实际交叉编译环境的建立？如何去除这几个错误啊？按照这样的表述来说，我的内核编译及头文件建立成功了吗？
