To make sure nolibc itself is compatible with -Wmissing-prototypes the compiler flag should be enabled when building nolibc-test. However some of its functions are non-static to ease debugging [0], triggering the compiler warning.
Disable the warning inside nolibc-test while still enabling it for nolibc itself.
