[issue15102] Fix 64-bit building for buildbot scripts (issue 15102)

It helps to build 64-bit binaries on a 32-bit Windows installation.
Normally, Python uses the python.exe it just built, but this fails if
the binary is a 64-bit binary, but the host is 32-bits.
It would be best if HOST_PYTHON was used if set, but it otherwise
falls back to using the Python just built.
I'm fine with dropping HOST_PYTHON for 3.4, but not for 3.3.

I see the errors, but I believe the solution is incorrect. It must
be possible to build from the command line exactly in the same way
as from the IDE, and it *was* possible to do so with VS 2008. We
just need to find out how to do it with VS 2010.

That is out of scope for this issue, then. If the file annoys you much,
create a separate issue.

Interesting. Now Rietveld doesn't show them anymore, either, in the place
where I left the comment.
