To avoid hardcoding further kernel configuration names for

make universe, split the logic into two parts:
- 1st to build worlds and generate kernel configs like LINT.
- 2nd to build kernels for a given TARGET architecture correctly
  finding all newly generated configs, not knowing anything about
  LINT anymore. (*)

(*) If you know better/cleaner/... ways to do this, let me know.
