>Description:
        on one of my boxes, build.sh sometimes fail due to spurious ENOENT.
        the following is an example.  ENOENT happens at different (random?)
        places for each runs.
        /tmp is tmpfs.  everything else are nfs.  the box has 4 logical cpus.

    compile  lib/archive_write_open_filename.ln
      build  libamu/libamu.so.4.0
