Compiled OpenCL binaries are not saved on Windows
Compiled OpenCL binaries are not saved into the cache directory, due to and upstream GLib bug with g_fopen().
Upstream bug is tracked here: https://github.com/Alexpux/MINGW-packages/issues/2414
I am keeping this one open until it's fixed in GTK+ and as reference.

As we have a workaround (https://github.com/darktable-org/darktable/commit/5ce5f85f39102e5abbc5214a9e1b1a9f1fa20f87), I'd close this bug.
