Add back i386-wine/Makefile (wouldn't commit otherwise).
Subversion and pre-commit hooks are not cooperating in the changes
required for i386-wine(-devel).
For the historians: This file is a copy of i386-wine-devel/Makefile as
at version 321106.
With the introducation of binary packages for i386-wine-devel the
port itself is largely complete (although there are still problems with
3D acceleration, both with and without nVidia).
