AFAIK, emacs doesn't support cross compiling.

I think the only difference is PATH has /mingw32/bin or /mingw64/bin,
and MSYSTEM is MINGW32 or MINGW64

At least for me, after doing

PATH=/mingw32/bin:$PATH
MSYSTEM=MINGW32

in a mingw64 shell, doing ./configure succeeds and I end up with a 32bit emacs.
