Hi Thomas,

> This commit updates the Buildroot manual for the variables used to
> indicate where to download the source code from:
> 
>  - It updates the description of <pkg>_SOURCE to make it clear that
>    Buildroot assume that the tarball is hosted at <pkg>_SITE.
> 
>  - It updates the description of <pkg>_PATCH to indicate that not only
>    file names (assumed to be hosted at <pkg>_SITE) can be used, but
>    also full URLs. This allows to match with what the current code is
>    doing.
> 
>  - It updates the description of <pkg>_EXTRA_DOWNLOADS to also
>    indicate that full URLs are now accepted, following the change made
>    in the previous commit.
