I looked into this further and its probably harmless (?) error caused by the
Docker default Apparmor profile in configure checks around max path:

 tar-1.34/m4/getcwd-path-max.m4:#define DIR_NAME "confdir3"
 tar-1.34/configure:#define DIR_NAME "confdir3"

I think it's harmless as its present on all other build workers as well.
