It works even without cross-compiling, since we're linking to msvcrt 
either way. (Which is, incidentally, why the commit message has always 
been "build with msvcrt" rather than anything like "build in PE format".)

We might generate warnings when not cross-compiling, but I don't know if 
that's worth fixing at this point.
