[Buildroot] [PATCH 2/6] pkg-download: Allow packages to pass an URL referer to the wget method

[Romain Perier]

Introduce a new package variable $(PKG)_DL_REFERER. When this variable
is defined, its value is passed to the wget downloader. Packages can now
retrieve archives from servers that assume that the HTTP client is
always connected to the website.
