[sp] Yes. When we need to be "extremely" small separate infra may be
     needed. But for rest, I feel we could/ should continue using the
     generic makefile infra - with more configuration options - that
     keeps maintenance low.

     I also feel that needs/requirements for the extremely small images
     will differ between the users. Maintaining compatibility will be
     a challenge for a common codebase.
