Explicit g++ 4.9 dependency breaks cross-building

This is still a problem:

# apt-get build-dep -aarmhf unity8
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages have unmet dependencies:
 g++-4.9:armhf : Depends: gcc-4.9:armhf (= 4.9.1-4ubuntu3) but it is not going to be installed
E: Build-dependencies for unity8 could not be satisfied.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm so tired of broken cross compile work flows I am going to figure it out.

The workaround for now is to edit debian/control of the package we are building and dropping g++ dep completely

This bug was fixed in the package unity8 - 8.02+15.04.20150109.2-0ubuntu1

I got an email overnight pointing to the following:

https://launchpad.net/~unity-team/+archive/ubuntu/ppa/+recipebuild/867970

From the build log:

The following packages have unmet dependencies:

Unable to resolve dependencies! Giving up...

Yeah, recipes are unhappy about the :native bit because they are usually ran on older stacks where dpkg didn't understand it yet. I've deleted the (outdated) recipes for now. I've got the unity-api fix in a silo right now, will release early tomorrow.

Thanks for that, much appreciate it!
