2.6.8 link failure for powerpc-970?

[Dan Kegel <dank@kegel.com>]

I'm trying to verify that I can build toolchains and compile
and link kernels for a large set of CPU types using simple kernel config files.
I'm also somewhat foolishly trying to do all this with gcc-3.4.2.
So any problems I run into are a bit hard to pin down to
compiler, kernel, or user error, since this is mostly new territory for me.

Here's one issue.
When I build 2.6.8 for powerpc-970 (using the config file
I got when I ran 'make allnoconfig' on 2.6.5; you can see it at
http://kegel.com/crosstool/crosstool-0.28-rc36/powerpc64.config),
I get a few link errors:

make: *** [.tmp_vmlinux1] Error 1

Is this user error for using an old config file, is it silliness
from gcc-3.4.2, or is something else going on?

Thanks,
Dan
