OK, thanks also to others who answered.  So the simplest method to do
this

    ./configure --host=i686-pc-mingw32 --build=i386-pc-linux-gnu

generically is

    ./configure --host=i686-pc-mingw32 --build=$(./config.guess)

Of course I set --host.  I hoped there is some shortcut for setting
--build as above.  But well, running config.guess is not that bad.
