Since rpm-build version 4.14.0-rc1(commit id: 4842adf), the new code will recompute the build-id of vmlinux when generating debuginfo, and results that the build-id is different from the boot image. Some debug tools, like perf, when we use `-k` to specify vmlinux, it would refuse to load vmlinux while detecing the build-id is different between vmlinux and the current boot image. We can use `$ file vmlinux` or `$ objdump -s -j .notes` to check vmlinux's build-id, and `$ hexdump /sys/kernel/notes` to check current boot image build-id. This patch is prevent build-id changing from generating debuginfo package. Signed-off-by: fu.lin <fu.lin10@huawei.com> Signed-off-by: yanglei <yanglei209@huawei.com>
