If avoiding the `target.json` is possible, definitely.

I didn't want to assume it is, though -- e.g. the native integer
widths you have is 64 but the built-in targets use 32:64 (perhaps
there is a way to tweak it with an LLVM param via `-Cllvm-args`, but I
don't see any obvious way from a quick look; `opt` does have it,
though).

(That is why we supported `target.json`, since it gives the most
freedom in the beginning.)

Cheers,
Miguel
