[Python-Dev] Windows make_buildinfo changes in 2.6 and cross-compilation

I ran across this while trying to upgrade our company's internal Windows CE
build from 2.5.2 to either 2.6 or 3.1.

In the 2.5 era, the Windows version of make_buildinfo used to fall back to
just copying the getbuildinfo.c file from \Modules if subwcrev failed; since
2.6, make_buildinfo fails the build if the compilation of getbuildinfo.c
fails when make_buildinfo is run, without falling back to copying.

Any reason not to keep the fallback strategy in the process?

The new process fails in cross-compilation scenarios (like building for
Windows CE on a Windows host) because, while the VC++ solution can be told
to build native (win32) binaries for make_buildinfo and make_versioninfo,
when make_buildinfo tries to compile via its hardcoded call to cl.exe, it
tries to use the cross-compiler without the required flags from the
cross-compilation configs in the vcproj files.
