Build log for gcc-5_5.1.1 on sparc64

Hello!

I'm currently working on bringing the sparc64 port of Debian back on track and
as part of that, I tried building gcc-5_5.1.1. Unfortunately, the build fails
at stage 3 with:

Attaching the build log, let me know if you need more info. I have full root
access to a very fast sparc machine with a sparc64 build root, so I can do lots
of testing etc.
