+Subject: [PATCH] override CPPFLAGS, CXXFLAGS and CFLAGS in Makefile
+
+When CPPFLAGS is passed on the command line, include paths for the
+bundled libraries are lost. Since the hand written Makefile want
+to use them unconditionally, we need to use the key word "override"
+before CPPFLAGS.
+
+Do the same for CXXFLAGS and CFLAGS otherwise -fPIC is lost.

+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)."
