[Daniel Sanders via cfe-dev]

Hi Sylvestre,

I tried to reproduce the mipsel build failure in a Debian chroot on my CI20 and my build gets further than buildd.debian.org did.  I tried to match the config and process described in the logs in the hope that I'd end up with the roughly same environment but I ended up with some differences. The toolchain package differences were:
	Binutils: 2.26-11 (the log had 2.26-10)
	g++: 5.3.1-3 (the log had 5.5.4.0-3)
	gcc: 5.3.1-3 (the log had 5.5.4.0-3)
	libstdc++-5-dev: 5.4.0-4 (the log had 5.4.0-3)
	libstdc++6: 6.1.1-6 (the log had 6.1.1-5)
	linux-libc-dev: 4.6.1-1 (the log had 4.5.5-1)
One process difference is that instead of running dpkg-buildpackage, I ran the underlying commands. I stopped after a successful 'debian/rules build' command since the last command it printed was the one that failed in the buildd log.

If you can narrow the problem down a bit then I can investigate further. Also, if you need help narrowing it down then I may be able to put you in contact with a colleague who works on Debian.
