building kernel: make[2]: execvp: ./sync-check.sh: Permission denied

Created by: limiter121

I am trying to update the linux-postmarketos-mainline package to the latest mainline release (currently 4.15-rc1), but doing so seems to break the build. The code is available on my fork.

Last lines of the log:
