Complete basic build process

We now have generation of an import library for linking against the Xbox
kernel, linking together an .exe, and converting it to an .xbe via cxbe.
Some further development of tooling aside (including filling in some
features in cxbe to better match the original JSRF executable), all that
remains now is to write decompiled code.
