make dkprintf() evaluate its parameters always
...
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled. Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".

clone(): do not allow setting CLONE_THREAD and CLONE_VM separately
...
XXX: When CLONE_VM is set but CLONE_THREAD is not the new thread is
meant to have its own thread group, i.e., when calling exit_group()
the cloner thread wouldn't be killed. However, this is a problem on
the Linux side because we do not invoke clone in mcexec when threads
are created. Thus, currently no support for this combination is
provided.
