test_cargo_compile_custom_build::code_generation is flaky on windows

[alexcrichton]

I'm not really sure why, I'm ignoring it for now. The logs are:

failures:

I haven't seen this in awhile, so closing.

Maybe we haven't seen it in a while because of the #[cfg(not(windows))] // FIXME(#867)?

Heh we this has been closed for almost 3 years so I've certainly lost all context on this...
