buildsys: handle ac_cv_cunit as a true cache-val

The ac_cv_-prefix variables are supposed to be settable from the command
line, à-la: ./configure ac_cv_foo=no

The canonical way of doing so is to use AC_CACHE_VAL() or AC_CACHE_CHECK().
The latter is to be preferred in our case, as it handles printing the
message for us.
