Instead of having the run_command function setting the
env from the buildEnv, this is the dependency that create the
env and then pass it to the run_command function.
This way, each dependency will be able to set a specific env.
By building kiwix-android on the `android` platform, we can now build
`kiwix-lib` on all `android_<arch>` platforms, and so have all
architectures in the same apk.
Fix#108
This is the big change !!!!
Instead of handling target as primary object and prepare/build targets,
we are handling build steps.
A build step may be a source (preparation) or a build (of the source).
Actualy, a step is a tuple (context, Builder or Source).
The context define the context of the step. It can be :
- 'source', for a Source step
- 'neutral' or the name of a platform for Build step.
Target becomes a "Class only" class.
