Possible regression in gcc 5/6 on m68k


The latest package versions of gcc-5 and gcc-6 seem to have suffered a
regression, both fail to build from source with the comparision of stage
2 and 3 failing:

Comparing stages 2 and 3

I am currently test-building a previous, known to be working version
of the gcc-5 package to make sure it's not a regression in my build
environment. If it turns out to be a gcc issue, I will report the
bug upstream.
