[Buildroot] [PATCH] core/pkg-generic: store file->package list for staging too

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

Thomas, All,

On 2017-02-24 11:14 +0100, Yann E. MORIN spake thusly:
> Currently, we store the list of files installed in target and associate
> each of them to the package that installed it.
> 
> However, we sometime may need to know what package installed which file
> in staging too, for example to debug header collision.
> 
> Enhance the step instrumentation to also generate the list for staging.
> 
> Only redirect once, not for each added file.
> 
> Also remove the intermediate files.

Arg, forgot to run "git commit --amend" before sending...
