Build blazecli for more targets

It can come in handy to have blazecli readily build for more targets,
especially for Android, where it can be especially painful to get a
working build from scratch.
This change adjusts the build workflow to use a proper cross compilation
setup that makes it easy for us to accomplish the same. With that in
hand, it adds builds for a few Android targets.
