travis: Enable Windows cross-compilation

We unfortunately can't run tests as they require running the just build
(foreign) executable, but at least it tries and build the Windows code
paths.

+# A script to automate setup and build for Windows cross-compilation

+# What it does:
+# 1) prepare a build directory
+# 2) download and unpacked the dependencies
+#    (see http://www.gtk.org/download/win32.php)
+# 2.1) fixup the unpacked pkg-config file paths
+# 3) setup the few required paths
+# 4) configure with sensible options for this
+# 5) build
+# 6) install in a local directory
+# 7) pack the installation in a ZIP file, ready to be used
+#    (but does not pack the dependencies)
+
+# You may change those
