That will be quicker than git bisecting on these machines (old > SGI machines). Can't stay stuck on 4.9.x forever... Can you also nail the issue down to using --disable-checking? For the powerpc case I think we run into a miscompile of stage2 and thus genmatch.c is really only the trigger and wouldn't be the place for a fix (well, maybe a workaround is fine for the GCC 5 branch here)
