The best way is to enable BR2_PRIMARY_SITE_ONLY=y. If you set this
option, Buildroot will only ever look for source code in two places:

 * In the local cache, indicated by BR2_DL_DIR, which defaults to the
   dl/ folder.

 * In the HTTP/FTP server indicated by BR2_PRIMARY_SITE, which is empty
   by default.

So basically, if you set BR2_PRIMARY_SITE_ONLY=y, and leave
BR2_PRIMARY_SITE empty, Buildroot will only look into the local cache
and not download anything from the network.
