FAQ
1. No rule to make target 'certs/rhel.pem', needed by 'certs/x509_certificat
解决：
修改.config文件
CONFIG_SYSTEM_TRUSTED_KEYS=""
2. BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make[3]: *** [vmlinux] Error 1
解决：
修改.config文件
CONFIG_DEBUG_INFO_BTF=n
