make: *** /lib/modules/5.10.134-13.2_alpha1.an23.aarch64/build: No such file or directory.  Stop.

经过定位发现：
build 为一个空的路径，软连接存在错误。
build -> ../../../usr/src/kernels/5.10.134-13.2_alpha1.an23.aarch64

How reproducible:


Steps to Reproduce:
1. rpmbuild -ba kmod-rds_prefetch_tuning
2.

system-rpm-config里面添加了软连接处理，将绝对路径换成了相对路径导致的问题。
已回退：https://gitee.com/src-anolis-os/system-rpm-config/pulls/32

内核需要rebuild
Comment 2 xuchunmei alibaba_cloud_group 2023-05-04 10:31:43 UTC 
内核已更新。
