gcrypt windows build is done on linux, uses wine to run test suite

[Dan Kegel]

Here's an interesting tidbit.  gcrypt's windows version's only
supported build environment is mingw on unix/linux, and
it relies on wine to run its test suite.

Use wine.  Just install MinGW and Wine under Linux, and then build
libgcrypt like this:

./configure --host=i586-mingw32msvc --build=i686-pc-linux-gnu

It will invoke the self-tests automatically, if you have the
binfmt-support package installed.

If you want a makefile that does everything, check out
