You can even let your generator generate the strcmp sequence.

I would probably go for some sort of

     struct {
        uint32_t start;
        uint32_t size;
        char name[24];
     };

and let my generator build an array of that. Last time I did that, I
stored the structs in the flash as well, to get independence between the
program and data images.
