Bug#819278: llvm-toolchain-3.8: FTBFS when built with dpkg-buildpackage -A (tests fail)

[Santiago Vila]

Package: src:llvm-toolchain-3.8
Version: 1:3.8-2
User: sanvila at debian.org
Usertags: binary-indep
Severity: important

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(i.e. only architecture-independent packages), and it failed.

In fact, I tried twice.

The first time this is what happened:

I doubt "dpkg-buildpackage -A" is related to this failure, but since
it takes 10 hours to build in a fast i5 machine, I have not had time
to try without -A, sorry.

The build machine was a QEMU/KVM virtual machine with 4GB + 4GB of
RAM/swap in the first case and 8GB + 4GB of RAM/swap in the second
case.

BTW: I have not looked at debian/rules, but please do not hide output
while the tests are running! We want to know what's happening!

Thanks.
