[Buildroot] Possible documentation error and a patch

[jerry at chordia.co.uk]

Greetings. 

I think the example here
http://nightly.buildroot.org/manual.html#outside-br-custom has a couple of
typos?

The example layout has $BR2_EXTERNAL_BAR_42_DIR instead of
$BR2_EXTERNAL_BAR_42_PATH in a couple of places and the source lines in the
example config.in are incorrectly quoted.

If I've read this correctly please find patch attached.

BR,

Jerry
