    labs/sysdev-tinysystem: no further shared library needed
    
    With Musl, the loader also turns out to contain the C library.

 If you still get the same error message, work, just try again a
 few seconds later.  Such a delay can be needed because the NFS
 client can take a little time (at most 30-60 seconds) before
 seeing the changes made on the NFS server.

 without the static compilation option, so that BusyBox takes
 advantages of the shared libraries that are now present on the target.
