make it reliably compile for amd64 on windows

This makes it possible to just pass `-8` to ./waf configure on Windows
and it will build 64-bit binaries. Yay I guess.

However, it's completely broken conceptually -- it ends up just brute
rewriting `conf.env.DEST_CPU` from `amd64` to `x86_64` at one particular
point in wscript. Why? Because many places in build system expect
`x86_64` as 64-bit DEST_CPU, especially breaking SDL2 lib detection.
Some of these are in waifu and patching that is beyond what I can hold
in my head right now.
Why that particular point? Because it DEST_CPU gets rewritten a few
times before that and no times after it seems.

This does not address `./waf msvs` VS project generation yet -- it will
still produce only Win32 platform that needs to be manually rewritten.

There's a mechanism for msvs extras to be passed a set of platforms, but
I've yet to make it work.
