Subject: [PATCH 1/4] io: remove deprecated sysctl.h

glibc 2.32 removed <sys/sysctl.h>
But since it is only required with __CYGWIN__ it can be removed safely
See related Issues upstream:

Subject: [PATCH 2/4] io: add static linking

When executing the programm the libraries were relinking to libm.so and
segfaulting
Since the libs in question are all <1MB when staticly linked this seemed like an easy workaround
To find future regression the interpreter will be called in
installCheckPhase

io: add install check
