I tried (based on the versions given by Paul):

git checkout v3.7-rc7
make ARCH=i386 defconfig
make -j64 bzImage

git checkout v3.8-rc7
make ARCH=x86_64 olddefconfig
make -j64 bzImage

but it built just fine. The build bug might depend on the
specific config file, or might depend on tooling details?
