bug#56505: [PATCHES] Mingw configuration for openssl

[Ludovic Courtès]

Good idea.

I think that’s good!

Added a commit log to this one and committed, thanks!

‘guix build openssl --target=x86_64-w64-mingw32’ works and the funny
part is that .dll files end up in bin/, but I think that’s intended on
Windows?
