Build kernel-4.19 in out-tree way is failed

【标题描述】Build kernel-4.19 in out-tree way got failed
【环境信息】
Hardware: D06
System:
NAME="openEuler"
VERSION="20.03 (LTS)"
ID="openEuler"
VERSION_ID="20.03"
PRETTY_NAME="openEuler 20.03 (LTS)"
ANSI_COLOR="0;31"

kernel version: 4.19.90-2003.4.0.0036.oe1.aarch64

【问题复现步骤】

create a kernel source tree with kernel-4.19 branch of 'https://gitee.com/openeuler/kernel'
mkdir -p /path/to/different/directory (which is the output directory of out-tree kernel build)
perform the out-tree kernel build sourced from the kernel-4.19 tree
cd kernel-4.19 tree
make O=xxxx openeuler_defconfig
cd xxx (xxx is the output directory)
make Image.gz

【预期结果】
The build should be successful.

【实际结果】

Failed as below:

Error 1

Error 2

【附件信息】
NA

您好，

我本地这边找了几台环境都没有复现这个问题。

查看了下certs 内核 build 的流程，怀疑是因为 touch 的时候 certs 目录没有创建，因此导致出现

Can't open certs/x509.genkey for reading, No such file or directory

目前看到这块 touch 的处理时，是如下补丁引入的
KEYS: Introduce load_pgp_public_keyring()

diff --git a/certs/Makefile b/certs/Makefile
index 5d0999b9e21b..5053e3c86c97 100644

我会后面找作者了解下情况。

谢谢参与 openEuler, 社区有你更精彩

由于我本地复现不出来，因此麻烦帮忙把你那边环境 make 的调试信息打出来提供下

make 后面添加 --debug=all 和 -n 参与可以提供更多的调试信息。
内核提供了 V=1 选项，调试内核的构建流程
因此执行make 的时候请加上如上的参数，然后把 build log 导出来提供下，谢谢

make -n --debug=all V=1 | tee -a build.log

然后把 build.log 提供出来
谢谢

I made a fix in certs/Makefile, then everything is OK.

ifdef CONFIG_PGP_PRELOAD_PUBLIC_KEYS
#ifneq ($(shell ls certs/pubring.gpg 2> /dev/null), certs/pubring.gpg)
#$(shell touch certs/pubring.gpg)
#endif
#$(obj)/system_certificates.o: certs/pubring.gpg

$(obj)/system_certificates.o: $(obj)/pubring.gpg
$(obj)/pubring.gpg:
$(Q)touch $@
endif

But I don't understand why we need to touch this 'pubring.gpg'
Actually, in 5.10, there is no this processing.

Anyway, I will send a patch for review.

Thanks!
