No, it always need to be there "by design". The number of interrupt
users (the interruptors) is determined at link time and is only
reflected in the __INTERRUPTOR_COUNT__ symbol which therefore con only
be read at runtime.

There's no symbol being undefined if (and only if) there's at least
one interrupt user so there's no way to link in something
