doc: Update mingw cross compile instructions

Browse Source 
The "Cross compilation for Windows with Linux" section of qemu-doc.texi
still instructs the user to use 'configure --enable-mingw32'
even after the option was removed in Aug 2008:
http://git.savannah.gnu.org/cgit/qemu.git/commit/?id=cd01b4a312248dd4e12c3d389d1a349cea4015d8

This documentation only change updates the instructions to:
* Remove use of '--enable-mingw32' in the configure example
* Correct the 'sdl-config' script name
* Remove references to i386-mingw32msvc.tar.gz which no longer exists in
  recent SDL releases
* Document the zlib dependency

Configure QEMU for Windows cross compilation:
@example
./configure --enable-mingw32
PATH=/usr/i686-pc-mingw32/sys-root/mingw/bin:$PATH ./configure --cross-prefix='i686-pc-mingw32-'
@end example
If necessary, you can change the cross-prefix according to the prefix
chosen for the MinGW tools with --cross-prefix. You can also use
--prefix to set the Win32 install path.
The example assumes @file{sdl-config} is installed under @file{/usr/i686-pc-mingw32/sys-root/mingw/bin} and
MinGW cross compilation tools have names like @file{i686-pc-mingw32-gcc} and @file{i686-pc-mingw32-strip}.
We set the @code{PATH} environment variable to ensure the MingW version of @file{sdl-config} is used and
use --cross-prefix to specify the name of the cross compiler.
You can also use --prefix to set the Win32 install path which defaults to @file{c:/Program Files/Qemu}.
Under Fedora Linux, you can run:
@example
yum -y install mingw32-gcc mingw32-SDL mingw32-zlib
@end example
to get a suitable cross compilation environment.
@item You can install QEMU in the installation directory by typing
@file{make install}. Don't forget to copy @file{SDL.dll} in the
@code{make install}. Don't forget to copy @file{SDL.dll} and @file{zlib1.dll} into the
installation directory.

Note: Currently, Wine does not seem able to launch
QEMU for Win32.
Wine can be used to launch the resulting qemu.exe compiled for Win32.
