I agree that using EXEEXT is better than HAVE_W32_SYSTEM.  Also, I agree
that we don't need to use detected yat2m for !CROSS_COMPILING.

Furthermore, I also think that the detection of yat2m on build system is
not needed for CROSS_COMPILING now, because we can build
yat2m-for-build.

Remaining problem is we need to have something like EXEEXT for build
machine, so that we can support cross building on Windows (say, for
POSIX machine).

Here is my attempt.  How do you think?
