The master can ask the slave to execute arbitrary commands. So, as long
as you implement the necessary steps as well-known commands executable
by the slave, you can then tell me how to insert them inside the build
process.

However, the only point of setting up an Android buildbot would be if:
1) Python actually builds correctly on Android
2) someone monitors the buildbot for failures and tries to act on them
