Subject: [PATCH 13/13] Modify wandboard to include the "distro defaults"
 header, so that all the config options distros expect are enabled. Remove any
 #defines that enable the same options from the wandboard files.

Update the wandboard boot scripts in the default environment to

a) Make use of the new "exists" shell command to avoid some error
   messges.

b) Allow booting using the sysboot command and extlinux.conf. This
   allows easy creation of boot menus, and provides a simple interface
   for distros to parameterize/configure the boot process.
