[Spice-devel] [PATCH spice-protocol 3/5] build-sys: Allows spec file to build MingW packages

[Frediano Ziglio]

Add MingW support. This allows to build MingW packages easily with a

  $ rpmbuild -ta spice-protocol-XXXX.tar.bz2

It's possible to disable MingW build using

  $ rpmbuild --without mingw -ta spice-protocol-XXXX.tar.bz2

This is base on some work by Eduardo Lima adding MingW support to SPEC
files.
Part of dependencies, description and names came from Fedora SPEC file
for mingw-spice-protocol package.
