testing "go 1.5 for trusty"

[Michael Hudson-Doyle]

Hi all,

As part of the plan for getting Go 1.5 into trusty (see here
https://wiki.ubuntu.com/MichaelHudsonDoyle/Go15InTrusty) I've built
packages (called golang1.5-go rather than golang-go) for trusty in my
ppa:

https://launchpad.net/~mwhudson/+archive/ubuntu/go15-trusty/+packages

(assuming 3:1.5.3-0ubuntu4 actually builds... I seem to be having a
"make stupid packaging mistakes" day)

I'll write up a SRU bug to start the process of getting this into
trusty tomorrow but before it does end up in trusty it would seem like
a good idea to run the CI tests using juju-core packages built with
this version of the go compiler. Is that something that's feasible to
arrange

The only packaging requirement should be to change the build-depends
to be on golang1.5-go rather than golang-go or gccgo.

Cheers,
mwh
