What about we add a fallback defition of the structure into
lapi/termio.h instead of disabling the test?

That way we would be able to test the kernel even if the userspace
headers were missing...

#include "config.h"

#ifndef HAVE_STRUCT_TERMIO
struct termio {
...
}
#ifdef

Should be enough to be able to compile that test, right?
