+Description: get rid of sysctl includes on Linux
+ The 'sysctl' syscall has been strongly deprecated on Linux for ages.
+ Currently, on old architectures it will spam syslog whenever used, and on
+ newer ones it's missing from the headers altogether.  Opencv has migrated
+ away on Linux already, but #include statements were left lingering.
+ .
+ This patch removes such #includes on non-__APPLE__, unbreaking x32.
