[Q] android kernel compilation giving error

I am new to android. i am try to compile android kernel 3.4.0 for HTC device.

After running cross compile command,

"export CROSS_COMPILE=/home/jharvard/ndk-x86/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-"

when I run make clean command

"make clean && make mrproper"

It shows errors,

/home/jharvard/kernel-code/linux/scripts/gcc-version.sh: line 25: arm-eabi-gcc: command not found
/home/jharvard/kernel-code/linux/scripts/gcc-version.sh: line 26: arm-eabi-gcc: command not found

I am not getting any clue to solve this error. Suggest me how to get rid of this error. Thank you in advance.
