2017-03-15syscalls: Adjust 'clone' to Guile 2.2.Ludovic Courtès
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.

2015-09-07build: container: Use the same clone flags as fork(3).David Thompson
The intent is to make 'clone' behave a lot more like 'primitive-fork', which calls clone(2) with SIGCHLD, CLONE_CHILD_CLEARTID, and CLONE_CHILD_SETTID flags.
