Running 'make O=/build/kernel binrpm-pkg' failed with below two errors.
Makefile:600: include/config/auto.conf: No such file or directory
+ cp make -C /mnt/root/kernel O=/build/kernel image_name make -f
/mnt/root/kernel/Makefile ...
cp: invalid option -- 'C'
Try 'cp --help' for more information.
Export KBUILD_OUTPUT when O= is used so that it could be used in locating
include/config/auto.conf
Use $srctree to locate source dir when generating image name, no matter
if O= is used.
