I think i had a similar issue. Mysys is missing the patch command. You need to install it.
I think i did this with the command pacman -Syuu patch in the command line.

Maybe it also helps to follow some of these steps: Bazel build with Windows

Sadly i can't build tensorflow on windows too... i just can't get it to work in anyway. :( I'm totally stuck but i really would need this to work.

This seems to be a problem of your WORKSPACE file. You need to import protobuf lib in your WORKSPACE file. For a working example using bazel with protobufs, you can take a look at our example here:
https://github.com/google/protobuf/blob/master/examples/BUILD#L13

Though since you are using bazel windows (which is at its very early stage of support), I suspect it's more likely to be a bazel issue here. You can probably try to ask it on a bazel forum instead.
