question about build kernel

[xiangfu]

the command:
cd linux-2.6.24/
wget 
http://svn.openmoko.org/branches/src/target/kernel/2.6.24.x/config/defconfig-2.6.24
mv defconfig-2.6.24 .config
make ARMH=arm CROSS_COMPILE=/home/xiangfu/bin/arm-angstrom-linux-gnueabi-

then the follow output:
arm-angstrom-linux-gnueabi-gcc: error trying to exec 'cc1': execvp: No 
such file or directory
arm-angstrom-linux-gnueabi-gcc: error trying to exec 'cc1': execvp: No

make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1
