交叉编译Kubernetes时出错

Question

I have been trying to cross-compile K8s running ./hack/build-cross.sh. I am getting this error, while building targets for arm64:

Any idea what could be causing this error? error.h is there on my system:

find / -name "errno.h"
/usr/arm-none-eabi/include/sys/errno.h
/usr/arm-none-eabi/include/errno.h
/usr/src/kernels/4.1.13-100.fc21.x86_64+debug/include/uapi/asm-generic/errno.h

/usr/include/sys/errno.h
/usr/include/bits/errno.h
/usr/include/errno.h
/usr/include/asm-generic/errno.h
/usr/include/linux/errno.h

Not sure what exactly is the issue, can anyone please help me with it?

I am using following arm packages:

rpm -aq | grep arm
arm-none-eabi-gcc-cs-c++-5.2.0-2.fc21.x86_64
gcc-arm-linux-gnu-4.9.2-5.fc21.x86_64
arm-none-eabi-newlib-2.2.0_1-6.fc21.noarch
binutils-arm-linux-gnu-2.25-4.fc21.x86_64
arm-none-eabi-binutils-cs-2014.05.28-3.fc21.x86_64
gucharmap-3.14.2-1.fc21.x86_64
arm-none-eabi-gcc-cs-5.2.0-2.fc21.x86_64
hdparm-9.48-1.fc21.x86_64

TIA.
