Hmm... It looks like you're probably attempting to build a 440 gcc
native binary to run on your 970s. I think from what you're
describing, when it bootstraps it dies.

I think you may well have to unfortunately build a cross compiler. I
have not actually done this in reality but I believe there are a few
guides out there. I think it's a matter of building with the right
--target flag, but it's possibly more complicated.

Found this which looks promising (I've been thinking of shifting my
ps3 compilation to my x86 boxen - I'll tell you how that goes)

Hope this helps pointing you in the right dir.
