Growing jujud.tgz sizes

[roger peppe]

Out of interest, why is the executable size a particular concern?
Cost of storage? Download times? Upload times?

FWIW I believe that executable sizes have gone up somewhat
with Go 1.1 because more metadata is being stored for the
more-precise garbage collector.

Also our (non-testing) code base has grown by about 40%,
from 37k lines in 1.10 to 52k lines now (not even counting new
external packages, for example gwacl) so some increase in size is to
be expected.

I would prefer to avoid changing the tools format in a backwardly incompatible
way unless we really need to.
