Set '-xe' instead of '-ex' for toybox
958cd56 
Toybox does not support `set -e` but it supports (buggy[1]) `set -x`,
alas it stops processing options on the first unsupported one, so make
`-x` first.

Does does not make toybox work though, because of another bug[2] in eval.

Sorry for the delay answering, I've got a bunch of todo items for the toybox shell and the design one I'm working on at the moment is a design issue with backslash line continuation. I've added this to the list, but at the moment I'm trying to go through and fix existing test suite failures in order. Happy to take more shell bug reports, and I am working through them, but... there's a list.
