From 59f084017e1d72471dcf4af4122b743cf60cbccb Mon Sep 17 00:00:00 2001

Subject: Change binary toolchain configuration, so that the options become
 visible just below the config, instead of at bottom of screen

Create a more useful default as toolchain path.

Allow generation of a script which sets up
paths to a binary toolchain generated by buildroot.
