Actually I remember now why this is necessary: there is not a simple way
to encode a string into a linker file as it has to be spit out byte
by byte. The autogeneration was the easiest way to make that happen.
Maybe there's some horrific c preprocessing or other generation that
could happen but I doubt that's any worse than the generated linker
