[automation] Produce Android x86_64 binaries

[ncalexan]

I noticed that we're not producing x86_64 binaries in automation. It might be a little difficult; see https://stackoverflow.com/questions/26779531/openssl-for-android-x86-64-and-mips64.

@ncalexan triaging this to backlog, please raise urgency as you see fit.

From slack conversation, it sounds like this may be required on or before August first due to:

I'm putting this back into "triage" for discussion based on the above.

From discussion with lockbox, we can do without this for a while, but it will become important in Q2. I'm going to set a calendar reminder to revisit this in March for further discussion.

It's March, we should discuss this again.
