[Buildroot] [PATCH next] package/pkg-luarocks: use <pkg>_EXTRACT_DEPENDENCIES

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2018-11-16 14:53 +0100, Thomas Petazzoni spake thusly:
> The host luarocks tool is needed when *extracting* luarocks
> packages. Since regular dependencies are only available at the
> configure step, it caused the "luarocks" program to be available too
> late to be used to extract luarocks packages.
> 
> To work around this, host-luarocks was manually added as a dependency
> of the extract step of luarocks packages. While this worked fine until
> now, it breaks badly with per-package folders, because host-luarocks
> is not recorded as an extract dependency of luarocks packages, and
> therefore is not copied to the per-package host folder, causing a
> failure.
> 
> In the mean time, the <pkg>_EXTRACT_DEPENDENCIES mechanism was added,
> which aims at fixing exactly this problem, so let's use it and
> simplify pkg-luarocks.mk.

> Cc: Francois Perrad <francois.perrad@gadz.org>
