With FTRACE disabled, doing cross-builds from the 2.6.26 amd64 client, a
setup that normally triggers the problem on the 2nd or 3rd build, I was
able to do 10 complete builds. ("make clean oldconfig vmlinux modules")
So it looks like ftrace is the cause, or at least provokes some other
usually-latent problem. I wasn't using it, so I'll just leave it off.

With those options enabled, I get this:
Running code patching self-tests ...
Running feature fixup self-tests ...
