So, I started looking at win32.mak and win64.mak, and couldn't resist
cleaning them up some more.

I removed the CPU argument altogether, but I also removed all references
to it within win64.mak, and replaced them with TARGET_CPU. The "setenv
/x86" or "setenv /x64" command that you can use in the Visual Studio
command line environment to choose the target platform sets TARGET_CPU.
So now you can use win64.mak to build 32-bit binaries too, just do
"setenv /x86" first.

Ideally, we could remove win32.mak altogether. But I don't understand
the differences well enough yet to go ahead with that. Thoughts?
