[Buildroot] [PATCH] sudo: optionally add user "default" to sudoers

[Stephan Hoffmann]

Hello all,

I think that using a non privileged user even in embedded systems is a
real good concept.

To make things easier I made this little patch that generates a config
option to add user "default" to the sudoers list when the package sudo
is included in the system.

Kind regards

Stephan
