Unable to cross compile for the phone

Same thing is happening to me, although I made the click chroot using click chroot .... create.

@Kyle:
Did you check my solution?
$click chroot -a armhf -f ubuntu-sdk-15.04 -s vivid maint apt-get download libsignon-glib-dev:armhf libsignon-glib1:armhf signond-dev:armhf
$click chroot -a armhf -f ubuntu-sdk-15.04 -s vivid maint dpkg -i --force-all *.deb

It works but breaks apt.

after installing the .deb with force as described above, I for example get this:

(click-ubuntu-sdk-15.04-armhf)root@vagrant-ubuntu-trusty-64:/home/vagrant# apt-get install libsignon-glib-dev:armhf

libsignon-glib-dev:armhf is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libsignon-glib-dev:armhf : Depends: libdbus-glib-1-dev:armhf but it is not going to be installed
                            Depends: libglib2.0-dev:armhf but it is not going to be installed
                            Depends: gir1.2-signon-1.0:armhf but it is not going to be installed
 signond-dev:armhf : Depends: signond:armhf (= 8.58+15.04.20151106-0ubuntu1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution)

@kyle: yes, they are now installed with dpkg instead of apt-get and building the go package should now work. That apt-get no longer works is what I meant with "broken apt". You forced an install that apt says is not possible and it's in a broken state. You can recover apt with (I think):

sudo apt-get remove -f signond-dev:armhf libsignon-glib-dev:armhf

Then apt works again, but the go package has missing headers.

It's only a hack until it's sorted out.

@Sam: ack :)
