OK I have hacked the makefiles to make cross-compilation
possible. It's a bit tricky because some parts of Wine need to be
compiled twice, since they are used both at compile-time and at
run-time. The way to do it is:

- create 3 empty directories: wine-src, wine-gcc, wine-mingw

- put the full source in wine-src, making sure you don't have any
  binaries in there

- in wine-gcc, do:
     ../wine-src/configure
     make depend
     make tools

- then in wine-mingw do:
     ../wine-src/configure --host=i586-mingw32msvc --with-wine-tools=../wine-gcc
     make depend
     make

This should build a full cross-compiled Wine. Of course most of it
doesn't actually compile at this point, but fixing that is left as an
exercise for the reader...
