Bug 905742 tracks progress made so far in building B2G Emulator builds for Darwin x86. Given some discussion I had with :coop and :aki, and the concerns expressed in https://bugzilla.mozilla.org/show_bug.cgi?id=905742#c58, it's worth considering whether it's possible for devs to provide instructions for a less convoluted setup and build procedure which can (relatively) easily be added to the build infrastructure, or to assess whether we can hold for now and determine such a procedure once we switch to a different version of android emulator.
