[Buildroot] [PATCH 2/2] docs/manual: document new behaviour of 'make printvars'

[Yann E. MORIN]

Arnout, All,

On 2019-03-12 18:55 +0100, Arnout Vandecappelle (Essensium/Mind) spake thusly:
> Add a 'VARS=...' setting to the example. To make it clear that several
> variables can be specified, use two variables in the first example.
> Only 2 variables are printed, so the ... is removed.
> 
> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be>
> Cc: Yann E. MORIN <yann.morin.1998 at free.fr>

Acked-by: "Yann E. MORIN" <yann.morin.1998 at free.fr>

Regards,
Yann E. MORIN.
