/bin/bash is not available on every system, nor always the default. /bin/sh is standardised, but not always the preferred interactive shell, hence it's configurable. There's no need to check for the existence of this shell during config, since it's an option that only affects run-time - and you may compile ncdu on a totally different system than you would run it on.
