There is another option to have the builder do everything mounted as a
tmpfs, so neither /tmp nor the working directory supports ACLs.  In this
case, the build also finishes successfully.

To summarize, the problem only seems to occur when /tmp supports ACLs,
but $WRKDIR (location where the tarball is extracted and the build
occurs) does not.
