[pkg-go] Bug#844515: packer: FTBFS on s390x (go install -v -p 1 died with signal 4)

[Daniel Stender]

Package: packer
Version: 0.10.1+dfsg-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Packer currently (recently 0.10.2+dfsg-1) fails to build on s390x:

<cut>
   dh_auto_build -O--buildsystem=golang
	cd obj-s390x-linux-gnu
	go install -v -p 1
dh_auto_build: go install -v -p 1 died with signal 4
	cd /<<BUILDDIR>>/packer-0.10.2+dfsg
debian/rules:6: recipe for target 'build' failed
make: *** [build] Error 255
dpkg-buildpackage: error: debian/rules build gave error exit status 2
<cut>

This is a regression from 0.10.1+dfsg-1 [1] (the build on 2016-10-16 [2] failed
for a dependency reason which is solved in the meanwhile, see #841605 [3]).

I can reproduce this locally in a qemu-chroot for Sbuild, however a test build on
the zelenka porterbox succeeded:

<cut>

Thanks for hints,
