1. Please describe the problem:
Check out https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10
Run `make dist-configs` on a system where /bin/sh is dash
The output is

Building /centos-stream/redhat/configs/kernel-aarch64-automotive-rhel.config complete
Building /centos-stream/redhat/configs/kernel-aarch64-automotive-debug-rhel.config ...

2. What is the Version-Release number of the kernel:
Head of main branch

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

It works with centos-stream-9

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Reproducible: Always
