[tz] Looking for a way to cut down binary zoneinfo size. Does anyone have the way to?

Thanks Paul!

I don't have Android, I have a much smaller vanilla Linux. We do use
zic in a toolchain.

Update on my progress: immediately after sending the email, I got
another idea: apparently, Rules need to stay in the source data, they
shouldn't affect the output size, as long as no zoneline uses them.
(hope it's correct)
I've tried cutting zonelines only, but now I get several of:

It also appears to me that some zones will be completely empty, and
thus should turn into Links (question is, to what?)
The project goes on.
