From: Alucryd <[email protected]>

This check will run 'bzr info' on the distant URL provided in the source
array and compare the branch root URL with the output of
'bzr config parent_location' run inside the local repo to make sure we
are building from the right sources. Previously, the check was only run
locally, as a result the local parent_location had to be used in the
source array. makepkg will fallback to this behavior for offline builds.
