one. However, using this method should be restricted to very
specific cases. Do not use it in the general case.
A Go package can depend on other Go modules, listed in its +go.mod+
file. Buildroot automatically takes care of downloading such
dependencies as part of the download step of packages that use the
+golang-package+ infrastructure. Such dependencies are then kept
together with the package source code in the tarball cached in
Buildroot's +DL_DIR+, and therefore the hash of the package's tarball
includes such dependencies.
This mechanism ensures that any change in the dependencies will be
detected, and allows the build to be performed completely offline.
