If configured, the primary site typically points to a mirror on the intranet
of an organization. The purpose of BR2_PRIMARY_SITE_ONLY is then to only
download from this mirror.
However, the organization may also have some local Buildroot packages
that download from a version control repository (git, hg, ...). In this case,
the mirror will normally not contain the sources, instead they should be
cloned via the version control tool. So in this case, BR2_PRIMARY_SITE_ONLY
cannot be used.
This means that the organization must resort to other means to make sure no
external downloads are performed.
This patch attempts to solve this situation by adding
BR2_PRIMARY_SITE_ONLY_EXTENDED_DOMAINS. This string option can contain
additional domains from which download is allowed when BR2_PRIMARY_SITE_ONLY
The organization can thus set:
to disallow any external downloads other than the primary site and the
mentioned version control domains.
