[oe] [PATCH] bash: add alternative configuration for bin/sh -> /bin/bash

[Chris Larson]

Be very careful with this.  Specifically, be sure to thoroughly test
installing bash onto a system that currently has busybox, and the
upgrade paths for both busybox and bash.  You never want to get into a
state, due to pre/post rm/install script execution order, where
/bin/sh doesn't exist.  If that happens, you won't be able to execute
the next script to fix it :)
