It shoulds like you're linking against host libraries, init does not
have to be static. My first guess would be that you did not compile gcc
final cross (2nd gcc build) with the specs patch. This would leave your
system attached to /lib/ld.so instead of /tools/lib/ld.so which is gone
once you chroot/boot. You can verify this by running readelf -l
/tools/bin/sh | grep interpreter
