Subject: support/download: relocate the git clone comment
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef92d32f19f1f92d78a42530ddb75355a9861d77;p=buildroot.git

support/download: relocate the git clone comment

Following commit 95a572282e87 (pkg-infra: move the git download helper to a
script, 2014-07-02), move the comment describing the shallow clone trickery as
well. Merge this comment with the existing helper comment that was added in
7e40a1103a91 (support/download: convert git to use the wrapper, 2014-08-03).

Rename $($(PKG)_DL_VERSION) to ${cset} to match the helper code context.
