This is achieved by writing soong.environment.used in Main() instead of as a side effect of a singleton. This makes a difference because build actions are not generated when GENERATE_BAZEL_FILES=true is set, therefore the side effect did not happen. Arguably, Main() is made worse by this change, but I don't want to tackle the problem of readably determining which mode soong_build is running in in this change. Test: Presubmits + the additional test. Change-Id: I66af2429aedf008762173eaaa55b828b4cf4328b
