I would take a look at lcc (there's a book about that) or ocaml as
examples of how it can be done; if you want more optimization, gcc is
an example, but it's harder to understand.

If you are interested in techniques for retargetable run-time code
generation, look at QEMU and GNU Lightning.

As for tools, you could look at stuff like Christian Collberg's ADT.

The alternative approach is, of course, to first go for portability by
writing an interpreter, and then increasing the speed of that. Read
some of my work for that.
