+Subject: [PATCH] remove sys/sysctl.h
+
+With musl irrlicht doesn't build due to missing sys/sysctl.h
+
+fatal error: sys/sysctl.h: No such file or directory
+
+From [1]
+"sysctl does not work, and NEVER worked. using it is bogus.
+it was a bogus experimental syscall that was deprecated before
+it was ever used (basically, a broken binary version of
+/proc/sys, without any stability between kernel versions for
+what the binary constants meant)."
