[ptxdist] /bin/sh link setting incompatibility when bash and dash installed

[Ian Abbott]

Hi,

Currently, the Kconfig option for BASH_SH (which causes /usr/bin/sh to 
be linked to bash) is as follows:

config BASH_SH
	bool
	default BUSYBOX = n || BUSYBOX_SH_IS_NONE

However, if DASH_LINK_SH is enabled, that will cause /usr/bin/sh to be 
linked to dash, resulting in a conflict.

I suppose the most robust fix would be to add a prompt to allow BASH_SH 
to be configured manually. I'm not sure if the default should be changed 
to `default (BUSYBOX = n || BUSYBOX_SH_IS_NONE) && DASH_LINK_SH = n`. 
If both dash and bash are installed, it is likely that dash would be 
used as the system shell and bash would be used as the interactive shell.

Imho, having both bash and dash only makes sense if /bin/sh is dash. So I
think changing the default as suggested above is the correct fix.
