At least the /etc/init.d/rcS - this one is run first.

if /sbin/init is from busybox, correct me if I'm wrong, so all that is needed
is to build busybox as static binary - there is a config option in busybox for
this.
strace is not in openwrt, yet.
I have made a port of 4.5.8 cris patch for 4.5.15. If someone could make the
openwrt package I'll provide the patch for cris architecture. To build strace
statically add '-static' flag to the final link command.
Regards,
Hinko
