Because we already discussed it earlier ;) - Without any
conclusion. The CONFIG_SHELL afaik comes from the kconfig legacy, but
other projects like U-Boot have recently skipped it and simply set

I have done it as well for buildroot, and a test build seems to work
fine, so I'll commit it in a moment. We still need to set CONFIG_SHELL
though for the kconfig stuff (or fix their makefiles, but I would
prefer to keep the difference between us and upstream minimal).

No, it currently falls back to /bin/sh if bash isn't there. We should
probably add a check in dependencies.sh
