when building the ocserv package on a multi-core machine
it randomly misbuilds man pages ocpasswd.8 ocserv.8 occtl.8
where one of them contains content that should have been in another

The problem goes away when changing
-make V=1 %{?_smp_mflags}
+make V=1

so there is probably some race condition
where the concurrently running man-page generators creates a single temp file
