2017-03-15syscalls: Adjust 'clone' to Guile 2.2....Before that, something like: (call-with-container (lambda () (match (primitive-fork) …))) would hang in 'primitive-fork' as the child process (the one started in the container) would try to pthread_join the finalization thread in 'stop_finalization_thread' in libguile, not knowing that this thread is nonexistent. * guix/build/syscalls.scm (%set-automatic-finalization-enabled?!): New procedure.
